Gibbs condemns Sykes joke about Limbaugh

From the ongoing daily briefing:  Press Secretary Robert Gibbs was just asked what the President thinks about comedian Wanda Sykes's joke about Rush Limbaugh.   Sykes' joked Saturday at the White House Correspondent's Dinner that Limbaugh was the 20th hijacker. Gibbs:  "I haven't talked specifically with him [about it], but my guess is there are a lot of topics that are better left for serious reflection, rather than comedy, I think there's no doubt that 9/11 is part of that."
