The House Judiciary Committee is investigating whether or not Attorney General Eric Holder lied under oath about his involvement in the prosecution of journalists for the disclosure of materials, officials said Tuesday. The latest development comes amid calls from both Democrats and Republicans for the attorney general to step down from his office. 

Which "Rubbish Argument" Did Gov Use to Get Rosen Search Warrant?

In testimony made on May 15 (watch in the clip below), Holder told officials he'd never been involved in the potential prosecution of the press. That statement, however, came just hours before reports surfaced that the DOJ had obtained a search warrant for the phone records and emails of Fox News correspondent James Rosen. It was made public last week that Holder personally signed off on the request for the warrant.

(Last week, Karl Rove predicted that the statement would come back to haunt Holder.)

"With regards to the potential prosecution of the press for the disclosure of material, that's not something I've ever been involved in, heard of, or would think would be a wise policy," Holder said in the May 15 testimony after it emerged that the DOJ had seized phone records of AP reporters.

In a fiery conversation during America Live, Megyn Kelly and Chris Stirewalt reacted to the breaking news, saying that the most important thing to come out of this investigation will be the discovery of how many other journalists were the subject of such warrants.

"If they have perjury as a means to pry stuff out of him, things could get very interesting," Stirewalt said, later adding, "You can't outrun stuff like this until you identify how many, how often, tell us why ... and until they give us that, we won't know how big and how bad this is gonna be."
