In 1998, the House voted to impeach Clinton's husband. In 2008, the House voted to hold Bush administration officials Harriet Miers and Josh Bolten in contempt. In 2012, they voted to hold the former head of the Justice Department, Eric Holder, in contempt of Congress. Twice in its history (most recently a century ago) they even had their sergeant at arms -- Congress's top cop -- arrest an administration official for not complying with a subpoena. Most recently, a key House panel voted on party lines to censure the head of the IRS. (That's a step below contempt, and the full House isn't even likely to vote on that.)
Chafetz is doubtful Congress will try any of that on Clinton. All those options are rife with drama and not necessarily commensurate with the situation at hand, when Republicans don't yet have answers about what law, if any, Clinton broke.
Well yes, I would hope that she broke a law if you're going to lock her up. At least as long as we remain a Democracy. This is just sad. What happened to the glory days of Benghazi investigations?
Congress could also launch its own investigation into Clinton's email servers, a la its recently finished investigation into the 2012 Benghazi terrorist attacks that happened under her watch. But that carries its own political risk. If they don't find a smoking gun that proves Clinton should be indicted, it gets harder for Republicans to argue that the system is rigged (as Donald Trump has tweeted) or at least not impartial (as Ryan has told reporters).
Can we move up the election? I'm anxious to get to the post-election kvetching.
