How many witnesses should Democrats request?
Mick Mulvaney may know more than John Bolton about what was going inside the White House. He was up to his eyeballs in attempting to cover up the hold on military aid to Ukraine.
Shumer has asked for a couple of other witnesses from the OMB. Who else could enlighten us on what was going on in Ukraine?
William Barr? He was mentioned in Trump's phone call with Zelensky. What else does he know?
Rudy Giuliani? He was at the heart of the corruption with Lev and Igor and Firtash and Shokin. He was directing it, at the behest of Donald J Trump.
The drawback with Giuliani is that he spreads so much bullshit that it is difficult to separate from useful information. Perhaps ask him simple "Yes" or "No" questions?
However many, there should be more witnesses called than just John Bolton.
The reciprocity idea being put forth by the Republicans is a bit like trading baseball cards and not appropriate, Dick Durbin suggested on CNN this morning.
