The head of the Special Olympics said today that Barack Obama called to apologize for his cringe-inducing gaffe on the Tonight Show, even before the episode aired last night, the AP reports. "He apologized in a way that was very moving," Tim Shriver told ABC. "He expressed that he did not intend to humiliate this population." Obama also invited Special Olympic athletes to the White House. On the show, Obama joked to Leno that his bowling "was like the Special Olympics or something."
