What if tRump refuses to answer questions?
I am guessing that Trump will not voluntarily submit himself for questioning to the FBI. I never thought he would. Instead, he will probably choose to stand on his claim that the FBI is bias and continue to spout off with his own opinion about collusion.
So, if he refuses to answer questions under oath, then what?
A Grand Jury subpoena?
And what itRump refuses to obey it?
tRump may still try the end run, firing Rosenstein and then making a recess appointment to fill his vacancy. In the meantime, I doubt we will see tRump submitting himself to the FBI for questioning.
