Rat talking point-call the witnesses, witnesses, witnesses. Like the magical, hidden unicorns have yet to be revealed.
Dems drumbeat for witnesses is nothing more than wanting to use this trial as their 2020 campaign stage. It would require another 4-6 months right up to election push.
Like a parrot aren’t they? Call the witness, call the witness awwwk! Call the witness. They would have to go some distance to be bird brains though.
