He did it to the Supreme Court justices during the State of the Union speech in 2010.
He invited Paul Ryan to his budget speech to attack him in front of TV cameras.
Last night, "President Thin-Skinned" Barack Hussein Obama, used the White House Correspondent's Dinner stage to mock Donald Trump, who was sitting in the audience, for asking questions about Obama's birth certirficate (Washington Times).
No one provided more comedic material Saturday evening at the White House Correspondents’ Association dinner than Donald Trump, who barely cracked a smile as President Obama and “Saturday Night Live” writer Seth Meyers cranked out the jokes for more than 2,500 guests.
“He can finally get back to focusing on the issues that matter, like, did we fake the moon landing,” Mr. Obama said. Before the president released his birth certificate this week, Mr. Trump had made casting doubt on whether the president was born in the United States a central part of his message.
Mr. Obama gave plenty of jokes about the criticisms he quieted this week by releasing his long-awaited birth certificate. Telling the audience he would also release his “birth video,” the screens played a clip from Disney’s “The Lion King” in which the character Simba is born.
Mr. Meyers, the headliner, offered his own round of Trump jokes, which included making fun of the billionaire businessman’s hair and his presidential aspirations.Seth Meyers showed everyone last night why Saturday Night Live is no longer funny.
Look, I'm not a fan of Donald Trump. I think he's doing this for publicity. He's right about the problems we face, but doesn't offer any real solutions, and I can't get behind someone who has given a ton of money to Democrat campaigns. But still, the childish manner in which this President acts towards critics and opponents is beyond the pale.
Perhaps Obama should have learned some lessons from the anti-bullying session he hosted at the White House, because he acts like a playground bully, with the lapdog media and the idiots of entertainment as his enablers.
