President Obama's remarks Friday about the tragic shooting of 17-year-old Trayvon Martin have prompted a diatribe from Newt Gingrich, who called them "disgraceful" and "appalling" on Sean Hannity's radio show. Obama offered his condolences to Martin's family and said, "If I had a son, he would look like Trayvon Martin." He also said all parents in America should understand why its imperative to investigate Martin's death. But Gingrich said Obama turned it into a "racial issue" that is "dividing this country up." Mitt Romney and Rick Santorum also weighed in on Martin's death yesterday, but neither of the two GOP presidential candidates attacked Obama.
