House Republican impeachment inquiry attorney Steve Castor on Friday baffled viewers with a line of questioning that appeared to be beneficial to House Democrats' case for impeaching President Donald Trump.

Among other things, Castor referred to ambassador Bill Taylor as a man of integrity and also didn't challenge former ambassador Marie Yovanovich's story that she had been the subject of a smear campaign launched by Trump attorney Rudy Giuliani.

In fact, Castor's line of questioning was so friendly to House Democrats, that some Twitter users joked that he was a "deep state plant" who's secretly helping to impeach the president.
