So you expect Hunter Biden to appear amid a withering storm of media hostility, take the stand, and say, "You got me, copper. I was taking $83 000 a month to funnel to a secret fund controlled by Barack Obama and Valerie Jarrett to undermine President Trump"?
Is that what you think will happen if Biden testifies?
No. I expect him to plead the Fifth which totally vindicates Trump for 2 reasons: (1) It justifies his demand for an investigation, and (2) The charges should be dismissed on principle because a key witnesss constitutional protections effectively block the defendants right to present evidence in his defense.
