Nothing will happen with this. Ronald Machen decides what happens to Eric Holder and if charges will be pressed. Yeah, I wish charges were pressed; I think executive privilege is a sham. Nixon tried to use it to avoid a subpoena and he had to resign. Holder does the same thing and he gets off free? Give me a break.
But Machen and Eric Holder were nominated by President Obama. So to think that one would screw over the other is naivety at best.
A CNN article lays out a few more reasons of why nothing will really happen to Eric Holder:
[Most legal observers] note that President George W. Bush’s Justice Department refused to take any action after a Democratic-controlled House voted in early 2008 to hold then-White House Chief of Staff Josh Bolten and then-White House Counsel Harriet Miers in contempt for actions relating to the controversial dismissal of several U.S. prosecutors.
They also note Obama’s use of executive privilege to prevent the release of certain documents in the Fast and Furious case — a move which typically makes executive branch officials immune from criminal prosecution.
Though maybe something will come of the House’s pursuit of civil action against Holder.
