All Nunes can do is refer DOJ officials to the whole House for a majority vote on whether to hold someone in contempt. If there is a majority vote for contempt, its referred to the DOJ for possible prosecution as a misdemeanor.
Nunes said he is seeking to impeach RR & Wray if they don’t comply. And what makes you think he would only do it only one time? We are talking about over 1 million documents here. The last thing the GOPe and coup plotters want is daily beltway theater on this subject on the eve of the midterms. Guaranteed.
That Nunes is still aggressively pursuing this after taking some many nukes should tell you he is playing for keeps here. Underestimate him at your own risk.
It takes a vote of 67 Senators to remove an impeached official from office.
