I believe Merrick Garland has been held in Contempt of Congress, previously. This time, I think they were voting to fine Garland $10,000 per day for withholding the tapes of Hur's interview with Biden. Yes, those four voted "no," but there were also a few Republicans who were absent for the vote that still could have swung it for approval. What I don't understand is why they didn't wait until those absent Republicans could be present for the vote.
