Update at 4:40 p.m. ET. House Votes To Hold Holder In Contempt:
In a dramatic showdown between the branches of government, the Republican-led House voted along party lines to hold Attorney General Eric Holder in contempt of Congress. This is the first time in history an attorney general has been held in contempt.
The battle between the Obama administration and the House Oversight and Government over the Fast and Furious operation just ratcheted up another notch. There's word that the White House is exerting executive privilege over documents that the committee's Republican majority has subpoenaed.
