Gibbs Attacks Limbaugh, Cheney as the "Republican Cabal" - Video 3/16/09

Here is video of White House Press Secretary Robert Gibbs responding to a question about comments by former Vice-President Dick Cheney that President Obama is seeking to take advantage of the Economic Crisis to radically expand government in all kinds of ways.

Gibbs responds that "I guess Rush Limbaugh was busy," so they "trotted out the next most popular member of the Republican cabal."

Question: As Gibbs makes the caddy remark, you hear some female hyena laughing in the background. I wonder which member of the impartial press corps it was who thought Gibbs was so funny?
