Sources tell KXAN Bolton defended former diplomatic and state department officials Fiona Hill, Tim Morrison, Alex Vindman, Bill Taylor, and Marie Yovanovitch.

“All of them acted in the best interest of the country as they saw it and consistent to what they thought our policies were,” said Bolton, during the question-and-answer time after his keynote speech.

He went on to say members of the Trump Administration should “feel they’re able to speak their minds without retribution.”

“The idea that somehow testifying to what you think is true is destructive to the system of government we have — I think, is very nearly the reverse — the exact reverse of the truth,” said Bolton.
