Among the documents being examined in the case of Trayvon Martin shooter George Zimmerman is a three-page medical file that says Zimmerman was diagnosed with a nose fracture, two black eyes, cuts on the back of his head, and a minor back injury the day after he shot Martin, according to ABC News. The medical documents were compiled by Zimmerman’s family physician when the accused murderer went to the doctor on the morning of Feb. 27, the day after he shot Martin. Zimmerman reportedly declined hospitalization after the shooting, but complained of “occasional nausea when thinking about the violence,” according to the report.

President Asif Ali Zardari of Pakistan will attend a summit of NATO leaders in Chicago this weekend, an embassy spokesman confirmed Tuesday. Relations have been strained between the U.S. and Pakistan over the last year since it became known that terrorist leader Osama bin Laden was hiding in the Muslim country, and as the U.S. has continued drone strikes against militants within the country. The president of Afghanistan is also scheduled to attend the meeting, at which leaders will discuss the future of the country. Taliban fighters in Pakistan’s tribal areas have been a continuing problem as Afghanistan tries to achieve stability before the U.S. withdraws most of its troops in 2014.

Republicans went for a fiscal one-two against President Obama Tuesday, with Mitt Romney jabbing the president from the campaign stump and House speaker John Boehner saying he’d repeat last year’s debt-ceiling stalemate if he didn’t see cuts in federal spending. In January of the coming year, $8 trillion in tax increases and spending cuts are scheduled to kick in for Americans, and Boehner said in a speech on Capitol Hill that it’s time to cut out more spending and extend the Bush tax cuts. “To get on the path to prosperity, we have to avoid the fiscal cliff, but we need to start today,” Boehner said. Democrats criticized Boehner for threatening to hold the country’s finances hostage to serve his party’s ends.

Forty percent of American adults click links, photos, and gifs of kittens on Facebook on a weekly basis. What aren’t they clicking, at least according to the users surveyed in a poll by the Associated Press and CNBC? Ads. That may be because most Americans who use Facebook don’t seem to much trust the social-networking site, with only 13 percent of users surveyed in a recent poll saying that they trust the site “completely” or “a lot.” That lack of trust in the site may hamper ad sales, even as the company prepares for what promises to be one of the biggest IPOs in history. In the AP-CNBC poll, a full 83 percent of those surveyed said they “hardly ever” or “never” click on Facebook ads. On Tuesday, General Motors pulled $10 million worth of ads from Facebook after the company felt that ads on the site may not be paying off.

And the winner is … Mitt Romney! The former Massachusetts governor had no problem running to victory in both Nebraska and Oregon on Tuesday night, winning nearly 70 percent of the vote in the Cornhusker State with three quarters of precincts reporting. The Associated Press called the race for Romney in Oregon, projecting him the winner of a distant second-placer Ron Paul. Rick Santorum placed second in Nebraska, though neither he nor Paul could get within 60 percentage points of Romney. Romney is set to gain 57 total delegates from Tuesday’s wins, 32 from Nebraska which will be added during the state’s convention in July, and 25 from Oregon to come when the win is made official. Former senator Bob Kerrey won the Democratic primary in Nebraska, setting up what promises to be a tight race with Republican state Sen. Deb Fischer, who won a three-way primary over Attorney General Jon Bruning.

What $2 billion loss now? The board of directors at JPMorgan Chase said on Tuesday that they still had confidence in CEO and Chairman Jamie Dimon, despite a $2 billion trading loss that occurred on his watch. The 50-minute meeting focused mainly on mortgage lending and servicing, and Dimon was asked very little about the trading loss. Under questioning after the meeting, Dimon said he is not against new regulation—and suggested that cutting executive pay could be used to make up the $2 billion. Meanwhile, the Justice Department opened a criminal investigation into the loss.

A bad omen, or just bad weather? Hours after he was sworn in as France's new president, François Hollande's plane was struck by lightning en route to Germany to discuss the Greek crisis with Chancellor Angela Merkel. The first Socialist to hold the office in 17 years battled stormy weather during his inauguration ceremony, after he tried to ensure that it would be as low-key as possible, with neither his children nor those of his partner, Valérie Trierweiler, in attendance. Hollande said he will try to “find a compromise” between Germany’s focus on austerity and Greek unrest.

A panel of 17 experts said Tuesday that the Food and Drug Administration should give its stamp of approval to a home HIV test, the first of its kind. The test approved in a unanimous vote requires users to take a mouth swab, then gives a result within 20 minutes. “I think the information suggests that this test could be very significant in helping to stem the number of new cases of HIV that occur every year,” said Blaine Hollinger, who chairs the panel. Some critics of the test have raised questions about its accuracy, but the benefits outweigh the harm of the occasional misdiagnosis, the panel said. According to the Centers for Disease Control, more than a million Americans live with HIV, a fifth of those who are said to be unaware of his or her infection.

Carlos Fuentes, a refined and elegant Mexican essayist and novelist, died Tuesday at the age of 83. After publishing his first novel, Where the Air Is Clear, at age 29, Fuentes rapidly made a prominent place for himself in Latin American literary culture. With an output that included political commentary and criticism as well as fiction, Fuentes was often considered a possible Nobel Prize recipient, but never received the award. The novelist gained notoriety for his strong leftist political views, and served as Mexico’s ambassador to England for several years. Fuentes’s final published work, an essay on French politics, was published on the day he died.

It’s back to Silicon Valley for screenwriter Aaron Sorkin—at least the Hollywood version of it, that is. The screenplay genius behind the blockbuster hit The Social Network will take on the life of Steve Jobs in a biopic that is said to be produced by Scott Rudin, it was reported Tuesday. The film is said to be an adaptation to Steve Jobs, the biography that was endorsed by the late Jobs himself and written by Walter Isaacson. Sony Pictures Entertainment said it was “confident” in Sorkin’s ability to capture Jobs, a person the studio described as “captivating, entertaining, and polarizing.” Sorkin was said to be Sony’s first and only pick for the job. This is the second large-scale Jobs movie, the first being done by Inferno Entertainment, showing now at Cannes and starring Ashton Kutcher.

Princes William and Harry gave rare interviews about their grandmother as part of Queen Elizabeth’s Diamond Jubilee. Katie Couric scored the interviews—with William at Buckingham Palace and Harry in an undisclosed tropical location—for an ABC special to air later this month. At one point, William tells Couric, “As I learned from growing up, you don’t mess with your grandmother.” And Harry says, “Behind closed doors, she’s our grandmother, it’s as simple as that.” The interviews, set to air May 29, also include a tour of Buckingham Palace.

Ellen DeGeneres might be doing the dance she’s famous for on her talk show at the sound of this news. The comedian joined an exclusive list Tuesday when she was named as the winner of the Mark Twain Prize for American Humor. Past recipients include Richard Pryor, Steve Martin, Whoopi Goldberg, George Carlin, Tina Fey, and Will Ferrell—last year’s winner—are just a few to receive the honor. DeGeneres, the Emmy-winning host of The Ellen DeGeneres Show, is being honored for her standup, activism, and books. Most recently she released a memoir in 2011 titled Seriously…I’m Kidding. DeGeneres will receive the award at the Kennedy Center Awards in Washington, D.C., in October. The 54-year-old already has several other awards, including 12 People’s Choice Awards and three Teen Choice Awards.

The fallen French politician isn’t going down without a fight. Dominique Strauss-Kahn has filed a $1 million countersuit against the Manhattan maid who accused him of sexual assault a year ago. In court papers filed Monday, DSK said Nafissatou Diallo had made “a malicious and wanton false accusation” that resulted in a lost French presidential bid and ruined “other professional opportunities.” Diallo’s lawyer has called DSK’s countersuit a “desperate ploy.” Strauss-Kahn may be forced to return to New York to face the civil case after a judge rejected his diplomatic immunity claim earlier this month. French officials are also investigating new allegations that the former IMF chief sexually assaulted a French prostitute at a Washington Hotel in 2010.

European Union naval forces on Monday night carried out their first raid on mainland Somali pirate bases—and said several of the pirates’ boats have been destroyed. Pirates based in Somalia are believed to be holding about 17 ships and 300 crew, including a Greek oil tanker that was attacked in the Arabian Sea just last week. The raid was carried out overnight and European forces said no Somalis were injured. While the EU has been reluctant to carry out a land-based attack for fear of the crew on the ships, the multinational forces recently agreed to expand operations to land as well as sea.

As John Edwards’s defense team began presenting its case on Monday, they announced the former presidential candidate’s 30-year-old daughter will testify this week on her father’s behalf—possibly as early as Tuesday. It is still undecided whether John Edwards will take the stand. While it’s unknown what Cate Edwards, a lawyer, will say that could help her father’s case, she could testify about her late mother, Elizabeth, and her father’s personal reasons for covering up his affair with Rielle Hunter. On Monday Edwards’s chief financial officer testified that Edwards had nothing to do with the financial reports filed to the Federal Elections Commission.

Risk managers and senior investment bankers reportedly expressed concern over the risky bets being made at JPMorgan Chase in the years leading up to the company’s $2 billion trading loss. Insiders say bosses, including CEO Jamie Dimon, were more concerned with gigantic losses coming from bad mortgages and new regulations threatening the profitability of traditional banking, and this led to a culture of weaker risk management. “There was a lopsided situation, between really risky positions and relatively weaker risk managers,” one former trader told The New York Times. Meanwhile, reports indicate that the bank may be reclaiming bonuses from employees involved in the snafu, including former chief investment officer Ina Drew, who resigned on Monday as a result of the loss.

Mitt Romney lept ahead of President Obama in a new nationwide poll Monday. The New York Times/CBS poll showed Romney at 46 percent and Obama at 43 percent. Last month the poll had found the two tied at 46 percent. 26 percent of respondents said that they were less likely to vote for Obama because of his position on same-sex marriage, while only 16 percent said that his announcement had made them more likely to vote for him.  Additionally, most of those polled think Obama’s newfound support of same-sex marriage is politically motivated. Meanwhile, 67 percent of those polled think he made the announcement “mostly for political reasons,” while only 24 percent think he did it “mostly because he thinks it was right.”

Patti Blagojevich, the wife of imprisoned former Illinois governor Rod Blagojevich, wrote a Facebook post on Monday night describing the prison visiting room as “one of the saddest places on Earth.” Blagojevich wrote that she had visited her husband at the Littleton, Colo., Englewood facility over the weekend, and that her husband was “so happy to see the [sic] us,” presumably meaning herself and the couple’s two daughters. But, she wrote, “that visiting room has to be one of the saddest places on Earth. All those little kids visiting their dads. It breaks your heart.” Rod Blagojevich began his 14-year prison sentence in March, and his lawyers said he has been put on cleaning detail washing pots and pans.

George W. Bush has surfaced from his postpresidential hibernation to endorse Mitt Romney. After his father, his brother Jeb, and even his mother backed Romney months ago, it seemed like G.W. might sit this one out. But Tuesday, just before the elevator doors closed on him as he was leaving a speech on human rights in D.C., Bush blurted out the words, “I’m for Mitt Romney.”

Louisiana Gov. Bobby Jindal defended Mitt Romney against attacks by President Obama on his record at Bain Capital. “President Obama hasn’t run anything before he was elected president of the United States,” charged Jindal, whose name is ocassionally floated as a possible VP for Romney. “Never ran a state, never a business, never ran a lemonade stand ... In contrast, Mitt Romney has been a successful governor, a successful businessman, he’s got the executive experience.” Former opponent Tim Pawlenty also defended Romney, saying, “Every third party group that has looked at that attack ad on the Obama election campaign has said it’s misleading, false and unfair.”

At least 21 people were killed in the town of Khan Sheikhoun when Syrian security forces opened fire Tuesday during a funeral procession. A rebel spokesman claimed that more than 50 people died in the attack, which took place during a visit of U.N. monitors to the town. None of the monitors were wounded, but the vehicles in which they were traveling were damaged. A United Nations spokesperson said the convoy was hit by an improvised explosive device, and the monitors were forced to use vehicles to flee.

Tucson, Ariz., police on Monday released the 911 call made when Isabel Celis, 6, disappeared from her bedroom last month. On the call, her father, Sergio Celis, calmly tells police he wants to “report a missing person” and that he “believes she was abducted from our house.” Isabel’s mother, Rebecca, made a second, more emotional, 911 call, telling the dispatcher that her husband had first noticed the girl missing from the family’s home. Police confirmed on Monday that they still believe Isabel was abducted, but they did not rule out her parents. Earlier on Monday, Isabel’s two brothers were placed in sole custody of their mother, saying Sergio Celis agreed not to have any contact with his sons.

President Obama joined the ladies of The View Tuesday, insisting that he really wasn’t mad when Joe Biden came out in support of gay marriage before him. “When you get to know Joe Biden, he is the most honest, straightforward guy,” he said. “He’s warm; he tells you what he thinks. We talked about it and what I said was I’m never going to blame anybody for telling what they believe.” He also said he doesn’t think the election will be defined by gay marriage and other social issues but by the economy. As for the more real issues, President Obama correctly identified which Kardashian sister was briefly married to Kris Humphries and admitted that on the subjected of Fifty Shades of Grey he was clueless. “I’ll ask Michelle when I get home,” he joked.

Mitchell Guist, one of the stars of the History Channel reality series Swamp People, died Monday night, a Louisiana sheriff said. Assumption Parish Sheriff Mike Waguespack said Guist had fallen while aboard his boat on the Intercoastal Waterway, near Pierre Part, La. The cause of his fall, and the cause of his death, is still unknown. Swamp People features residents of Louisiana’s Atchafalaya swamp country during alligator-hunting season. The network said Guist turned 49 on Friday.

A bill that would have allowed same-sex couples equal rights as married couples was killed on Monday night in a special legislative session. Although the bill had been likely to pass the state’s House of Representatives, Republicans rejected it, claiming the Democrats are trying to use it as an issue before the November elections. The bill went to the special committee known as the “kill committee”—because its members are in safe seats and can kill any bill they wish—on Monday morning by the GOP leadership. Republican state Rep. Don Coram, whose son is gay, voted against the bill, citing a 2006 vote by Coloradans to ban same-sex marriage, and he also said he believed Democrats are “playing politics” with gay marriage.

Greece will hold a new election at some point in the near future, a spokesperson for President Karolos Papoulias said Tuesday—just nine days after an inconclusive vote. Politicians have failed to form a government, and the uncertainty only prolongs the political crisis that could push the country closer to bankruptcy. Although Papoulias did not give a date for the election, rules dictate it will most likely happen sometime in mid-June. A caretaker government will be formed on Wednesday, a spokesman said. Polls show that the leftist Syriza, which rejects the bailout and came in second in the last election, holds the lead.

Rebekah Brooks, Rupert Murdoch’s onetime deputy, as chief of News International, was officially charged on Tuesday with “perverting justice” in the wide-reaching phone-hacking scandal. Also charged was her husband, Charlie Brooks; the two issued a statement calling the charges a “weak and unjust decision.” Brooks, 43, was editor of the now-defunct tabloid News of the World when reporters from the paper allegedly hacked into the voicemail of murdered schoolgirl Milly Dowler. In addition to hacking, Brooks has been linked to allegations of payments to police in an attempt to cover up the hacking, and many have questioned her close relationship with those in government, including Prime Minister David Cameron.

A masseur who accused actor John Travolta of sexual assault has dismissed the case, TMZ reports. The man alleged that Travolta assaulted him during a massage at the Beverly Hills Hotel on Jan. 16, but photos proved that Travolta had been in New York that day. A second accuser, who filed suit for an alleged assault in Atlanta, is still pursuing his claim against Travolta.

A Florida woman shot and killed her four children Tuesday before turning the gun on herself—just hours after she had unsuccessfully tried to kill the kids in their own house. The children, ages 12 to 17, had gone to a neighbor’s house for help before dawn after their mother shot them. The neighbor had heard the gunshots and called 911. But Tuesday morning, the mother approached the neighbor’s house calling for the children to come home, then fired fatal shots when they obeyed. The shooting took place in Port St. John , about 15 miles west of NASA’s Kennedy Space Center on Cape Canaveral.

Defense Secretary Leon Panetta has ordered the Air Force to restrict flights of its F-22 fighter jets due to continuing problems with oxygen supply on the jets. The Pentagon has turned to the Navy and NASA to help investigate why some F-22 pilots have experienced in-flight dizziness and other symptoms of oxygen deprivation leading to hypoxia, with Panetta ordering all F-22 flights to remain within a “proximate distance” of an airfield. The Air Force has so far been unable to determine the cause of at least 12 incidents of hypoxia in pilots, though a spokesman for the Defense secretary said he is determined to get to the root of the problem and that pilot safety remains “his first and foremost concern.”

For decades, Alzheimer’s has been a disease without a cure. But now, researchers at the National Institutes of Health may have found a way to prevent the often slow and difficult decline the illness inflicts on people’s lives. People who are genetically predisposed to Alzheimer’s but who don’t have any symptoms will be given Crenezumab, a medication that breaks up plaque that settles on the brain, to see if it keeps dementia from developing. The $100 million study will run for five years, but could see results in as little as two years.

When President Barack Obama made his historic announcement in support of gay marriage, political pundits went into overdrive trying to determine whether it would help or hurt him come November. A new Reuters/Ipsos poll released Tuesday revealed that, so far, the move hasn’t swayed voters much one way or the other. Roughly 31 percent of those polled now have a more favorable view of Obama, and 30 percent say they have a less favorable view. Forty percent say the announcement had no impact on how they’ll vote whatsoever. In the most important category—independent voters—tended to side against the president by just a hair, 26 percent of them viewing Obama less favorably while 19 percent now view him more favorably. Fifty-four percent said the announcement had no impact on their opinion.

General Motors has announced that it will stop advertising on Facebook after determining that the ads on the social-media site are ineffective. The announcement comes just days before Facebook’s highly anticipated IPO, estimated to be as high as $104 billion. GM has been reevaluating its marketing strategy in an effort to cut its $2 billion marketing budget. Company officials reportedly began doubting the Facebook ads earlier this year. After meeting with Facebook managers, they remained unconvinced. GM’s marketing chief said that the company “is definitely reassessing our advertising on Facebook, although the content is effective and important.” GM said Facebook remained a useful tool for engaging with its customers.

Worn by the queen of France at her inauguration in 1610, the Beau Sancy, one of the most famous diamonds in the world, was auctioned for $9.7 million Tuesday in Geneva. “It’s extremely rare for a diamond of this importance to come on the market,” said David Bennett, Sotheby’s chairman for jewelry. “It’s never been out of royal hands, it’s of immaculate provenance, it’s in all the history books of famous stones.” Apart from being worn by Medici, the jewel also played a role in English politics, and was pawned by Mary Stuart to help Charles II as he tried to grab back the English crown. But the buyer Tuesday was anonymous, and the gem may now be in common hands for the first time in its history.

The political rhetoric was as high as an elephant’s eye Tuesday as Republican presidential candidate Mitt Romney stumped in Iowa, saying President Obama has put the country on a financial course that “threatens what it means to be an American.” Romney claimed that a “financial crisis of debt and spending” has swept the nation, but the former Massachusetts governor and Bain Capital executive said he has the know-how to put the country right. “A prairie fire of debt is sweeping across Iowa and our nation, and every day we fail to act that fire gets closer to the homes and children we love,” Romney told supporters at a campaign stop in Des Moines.
