BOB SCHIEFFER: When the government's so called "Fast and Furious" program was created, the idea was to allow illegal guns to be shipped into Mexico so investigators could be traced into where they were going and get a better handle on where Mexico's criminal cartels were operating. The program has been a disaster. The guns have been linked to killings of Mexican officials and now it appears that Attorney General Eric Holder knew a lot more about it than he recently told congress. Here's Sharyl Attkisson.

SHARYL ATTKISSON:  New documents obtained by CBS News show Attorney General Eric Holder was sent briefings on the controversial fast and furious operation as far back as July, 2010. That directly contradicts his statement to congress. Listen to what Holder told a Judiciary Committee hearing on May third this year.

ERIC HOLDER, ATTORNEY GENERAL: I'm not sure of the exact date but I probably heard about Fast and Furious for the first time over the last few weeks.

ATTKISSON: Yet internal justice department documents show at least ten months before that hearing, Holder began receiving frequent memos discussing Fast and Furious. - October 3, 2011 CBS Evening News
