CNS News reported, via FOX Nation:

House Oversight and Government Reform Chairman Darrell Issa (R.-Calif.) told CNSNews.com in an interview that he believes the Justice Department is covering up information relevant to a congressional investigation of an operation in which the department knowingly allowed intermediaries of Mexican drug cartels to purchase guns at licensed firearms dealers in the United States and then get away without being arrested or the guns being retrieved.

Last December, two of those guns ended up at the scene of the murder of a U.S. Border Patrol agent who was killed by alleged agents of the Mexican drug cartels.

Issa pointed to two things he says indicates a Justice Department cover up. First, he cites a letter that Assistant Attorney General Ronald Weich, head of the Justice Department’s office of legislative affairs, sent to Sen. Charles Grassley (R-Iowa), the ranking member of the Senate Judiciary Committee on Feb. 4, 2011. Issa characterizes that letter as a “lie.”

Secondly, Issa says the Justice Department made excessive and unjustifiable redactions in documents it provided to his committee.

The Politico announced tonight that the ATF head will resign over the scandal.
