The dust-up between Fox News Channel and Rick Sanchez got uglier over the weekend after an anonymous Twitter account was created to highlight a 1990 accident in which the car Sanchez was driving struck a pedestrian who eventually died from his injuries.

Last Friday Fox ran a full-page ad in the Washington Post bragging about its coverage of the Tea Party protests the weekend before in Washington, D.C. In the ad Fox alleged its competitors ignored the march (presumably for ideological reasons). The ad text read: "HOW DID ABC, CBS, NBC, MSNBC, and CNN MISS THIS STORY?"

Fox's ad on Friday prompted a stinging response (video below) later that night from from Sanchez, who condemned "the fools who perpetuate falsehoods" and appropriated U.S. Rep. Joe Wilson's two-word outburst during President Obama's address to Congress by telling Fox, "You lie."

The very next day the anonymous Twitter account was launched. The bio of the account states: "Rick Sanchez: Drunk driving, Hit N'Run...dude ended up dying...now anchors at CNN 3PM"

The creator of "wreksanchez" was busy over the weekend, tweeting 268 times through last night. Some samples:

rick sanchez has been lying to all of his viewers about his past...google his name and drunk driving

@ricksanchezCNN is not a news anchor, he's a comedian for the events of the day...followed closely by his twitter/facebook possee

@ricksanchezCNN is a hero to many terrorists/criminals around the world and in prison.

I'm trying to prove that this man (@ricksanchezcnn) isnt worthy of giving us the news when hes commited such a notrocious act

While the accident did happen, it hardly has been covered up or hidden. It's mentioned in Sanchez's Wikipedia entry and the Miami Herald covered it extensively (Sanchez was a news anchor at a Miami station at the time).

It's hard to understand how this is relevant to the dispute between Fox and Sanchez. Perhaps the anonymous creator of the account should come forward to explain the connection. Otherwise we're left to assume it's nothing more than a smear job to discredit someone who called Fox on its inaccurate ad in the Post.

"Notrocious" indeed.
