Sen. Joe Manchin (I-WV) is at it again, giving senators on both sides of the aisle reason to be upset with him days before he finishes out his final term in the Senate.

The West Virginia independent kept all of Washington guessing on Wednesday ahead of a critical vote that would have handed Democrats a majority on the National Labor Relations Board. He ended up sinking the nomination of Chairwoman Lauren McFerran, meaning the seat will be open for President-elect Donald Trump to appoint when he starts his second term in January.
