It’s becoming increasingly clear that Attorney General Eric Holder lied under oath before the House of Representatives.

You’ll recall he told investigators he only learned of Fast and Furious through media reports following the program’s collapse. That would mean he only learned of the program’s existence sometime in early 2011. He pleaded ignorance before that.

But then recently we learned Holder received a briefing from the director of the National Drug Intelligence Center in July of 2010, which would mean he was briefed at least once about the program while it was still ongoing. Fast and Furious wouldn’t be shut down until after the murder of Border Patrol Agent Brian Terry and its connection to Fast and Furious went public.

Now Congressional investigators possess evidence showing Holder was briefed not once, not twice, but five times about Fast and Furious during the program’s existence. Those memos began in July 2010. The program wasn’t shut until late 2010. Holder claimed he first learned of the operation in early 2011.

 Senator Chuck Grassley and Congressman Darrell Issa today said that Attorney General Eric Holder received at least five weekly memos beginning in July 2010, including four weeks in a row, describing the ill-advised strategy known as Operation Fast and Furious. The memos were to Holder from Michael Walther, the director of the National Drug Intelligence Center.

The Attorney General told Issa during a House Judiciary Committee in May 2011 that he had just learned of Fast and Furious a few weeks before. Yet, on January 31, in a previously scheduled meeting, Grassley personally handed him two letters about Fast and Furious. Grassley and Issa said they find it very troubling that Holder actually knew of Operation Fast and Furious much earlier, and in greater detail than he ever let on.

The memos specifically said that the straw buyers were “responsible for the purchase of 1500 firearms that were then supplied to Mexican drug trafficking cartels.”

So Holder was quite aware of the operation, yet he told Congress under oath that he was ignorant of its existence until early 2011.

Either Holder lied under oath, which constitutes perjury, or he’s actively ignoring high-level briefings regarding his job. Either way he should not be occupying the office of Attorney General. He’s either a criminal liar or a negligent hack. Neither is acceptable in that office.
