The President lies once again: Holder knew about Fast and Furious as early as July, 2010:
"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."
