Legendary golfer Arnold Palmer died Sunday in Pittsburgh at the age of 87. Alastair Johnson, chief executive of Arnold Palmer Enterprises, confirmed the businessman, philanthropist, and trailblazing golfer died during the afternoon following complications from heart problems, several days after being admitted to the hospital for a cardiovascular procedure. “We are deeply saddened by the death of Arnold Palmer, golf's greatest ambassador,” the U.S. Golf Association said in a statement. “Arnold Palmer will always be a champion, in every sense of the word. He inspired generations to love golf by sharing his competitive spirit, displaying sportsmanship, caring for golfers and golf fans, and serving as a lifelong ambassador for the sport.” Palmer’s accessible public persona and dominance of the sport during the early days of the television era led to him being known as the “King of Golf.”

Several people were shot by an individual at a strip mall in Houston early Monday morning, according to the Houston Police Department. The exact number of injuries is unknown. According to ABC13, as many as six people were shot, including the shooter who was hit by officers and is now dead. Police first received a call about the incident at 6:29 a.m. CT. A bomb squad was brought in to examine the suspect’s car. “I literally heard the gunshots pass my face,” a witness told ABC13.

Dozens of airstrikes hit Aleppo overnight, said Syrian civil defense worker Bebars Mishal. “Especially at night, the bombardment intensifies, it becomes more violent, using all kinds of weapons, phosphorous and napalm and cluster bombs,” he said. “Now, there’s just the helicopter, and God only knows where it will bomb. God knows which building will collapse.” The airstrikes intensified after the short-lived ceasefire, brokered by the U.S. and Russia, ended. The Syrian army has reportedly launched a new offensive in the city. The U.K.-based Syrian Observatory for Human Rights said at least 237 people have died in airstrikes in Aleppo since last Monday, when the truce ended.

Donald Trump campaign manager Kellyanne Conway admitted Monday that Trump didn’t know if the NBC debate moderator Lester Holt was a Democrat or a Republican. Trump claimed he was a Democrat last week in an interview with Bill O’Reilly. Trump said, “It’s a phony system. They are all Democrats. It’s a very unfair system.” On Tuesday, several media outlets reported that Holt is, in fact, a registered Republican. But Monday on Morning Joe, Conway said Trump couldn’t have lied about Holt because “a lie would mean that he knew the man’s party registration.”

Janet Brown, the executive director of the Commission on Presidential Debates, said Sunday that she does not believe moderators should play a large role in fact-checking each candidate at the event. Speaking with Brian Stelter on CNN’s Reliable Sources, Brown said the candidates should be the judges of what the other says. “I don’t think it’s a good idea to get the moderator into essentially serving as the Encyclopedia Britannica,” Brown said. “And I think it’s better for that person to facilitate, and to depend on the candidates to basically correct each other as they see fit.” The first presidential debate between Donald Trump and Hillary Clinton is Monday night at 9 ET. NBC News’s Lester Holt is the moderator.

The mayor of Charlotte has lifted a curfew in the city after several days of protests following the fatal police shooting of a black man. Mayor Jennifer Roberts had imposed the curfew last Thursday as the protests spiralled out of control, with one demonstrator fatally shot during the protests. On Sunday night, however, Roberts said the curfew, from midnight to 6 a.m., would no longer be in effect. Protesters have continued to march through the city's streets since Keith Scott was shot on Tuesday, but the release of police video of Scott's death on Saturday seems to have calmed things down.

The U.S. Coast Guard rescued one of two Connecticut boaters who have been missing for an entire week. The two went missing Sept. 18, and the search was called off Friday before crewmen on a freighter found 22-year-old Nathan Carman on Sunday, adrift in an inflatable life raft. Carman was near the coast of Massachusetts. Carman and his mother, 54-year-old Linda Carman, went missing after leaving a Rhode Island marina for a fishing trip. According to reports, Nathan Carman was in good condition when he was found, but his mother is still missing. Coast Guard officials said they are investigating the incident and Carman was due back in port on Tuesday.

Two black U.S. medalists who were expelled from the 1968 Olympic Games for staging a protest on the podium have been invited to the White House. Tommie Smith and John Carlos, the two men featured in the iconic photo with their raised-fist protest at the Mexico City Games, have been invited by the U.S. Olympic Committee to attend a White House gala and meet President Barack Obama, Carlos told Reuters. The invite stands in stark contrast to the treatment the men received following their demonstration against racial inequality. The competitors in the 200-meter track event were suspended from the U.S. Olympic team over their protest and sent back to the U.S. “It was against the charter of the Olympic Committee to make a political statement at the victory podium,” Carlos told Reuters in a phone interview. At a time when the fight for civil rights in the U.S. was especially turbulent, the two men famously bowed their heads and thrust their fists into the air while the U.S. national anthem played. Carlos said he does not expect an apology from the U.S. Olympic Committee after all these years, but he does hope they have a better understanding of the protest now. “Time has gone by to the point where they had to take a look at themselves and say, ‘These guys weren’t bad guys,’” Carlos said. “‘They were courageous enough to make a statement for what they believed in.’”
