Rep. Christopher Cox, R-Calif., yesterday asked for a congressional probe into CBS for its use of allegedly forged documents in a story meant to prove President Bush attempted to shirk his duties in the Texas National Guard.

Cox penned a letter to Rep. Fred Upton, R-Mich., chairman of the Subcommittee on Telecommunications, asked for an official investigation “into the continued use by CBS News of apparently forged of documents concerning the service record of President George W. Bush intended to unfairly damage his reputation and influence the outcome of the 2004 presidential election.”

In his letter, Cox cites several news stories and opinions of experts who say the documents are fake and alleges CBS has purposely tried to damage Bush’s reputation ahead of November’s presidential election.

“Despite the growing abundance of evidence that CBS News has aided and abetted fraud, the network has declined to reveal the source of the disputed documents,” Cox wrote.

“Given the shortness of time between now and the election which the apparent fraud is meant to influence, and the even shorter time before Congress is scheduled to adjourn, I strongly urge that the Subcommittee move with all deliberate speed to uncover the facts.”

Despite testimony from experts about the apparently fraudulent nature of the memos, CBS anchor Dan Rather has stood by the story he first broke on “60 Minutes II” last week.
