“I thought a lot about if I had been in that position how would I have approached it, and I’ll be honest: It’s inconceivable to me that if I had firsthand knowledge of gross abuse of presidential power that I would withhold my testimony from a constitutional accountability process,” said Rice, who served in the Obama administration, Wednesday while sitting next to Bolton at an event at Vanderbilt University in Nashville.
“In no case did I say I would reject a subpoena,” he said.
“I can’t imagine withholding my testimony with or without a subpoena,” Rice countered.
“That, to me, makes it even more difficult, as a former national security adviser, not being willing to come forward,” Rice said. “I would feel like I was shamefully violating the oath that I took to support and defend the Constitution against all enemies foreign and domestic.”
“I will bet you a dollar right here and now my testimony would have made no difference to the ultimate outcome,” Bolton said Wednesday. “If anybody thinks to the contrary, I just don’t think you knew what was going on in Washington.”
“I’ve done the best I could in difficult circumstances,” Bolton said. “I sleep at night because I have followed my conscience.”
