Rush suggests Downing Memo a fake

Syndicated radio host Rush Limbaugh suggested that the Downing Street memo "may be a fake" and compared it to the disputed memos used by CBS in its controversial story about President Bush's National Guard service.
From the June 20 broadcast of The Rush Limbaugh Show:

LIMBAUGH: I purposely haven't talked about this Downing Street memo much because, frankly, a) it didn't interest me and, you know, if it doesn't interest me, I'm not going to talk about it. And the reason it didn't interest me is because it was just another one of these ginned up things by the libs, and it looks like it's got some similarities to Bill Burkett and the forged documents of CBS and Rathergate.
Later in the program, Limbaugh responded to a caller's question about the Downing Street memo by saying, "What is it? The Downing Street memo doesn't say anything, and it may be a fake. It may be a forgery."
