At today's White House press briefing, Robert Gibbs was asked how the president felt about comedian Wanda Sykes' joke calling Rush Limbaugh the 20th hijacker -- one the comedian herself conceded may have been "too much."

The press secretary began by saying he hadn't spoken with President Obama specifically about it, and stressed that the choice of the entertainment is made by the White House Correspondents Association. He even referred to the WHCA president, Associated Press reporter Jennifer Loven, seated in the front row as he addressed the topic.

"My guess is that I think there are a lot of topics that are better left for serious reflection rather than comedy. I think there is no doubt that 9/11 is part of that," said Gibbs.
