During our impeachment investigation, dozens of patriotic public servants did what was right, They risked—and some lost—their careers and livelihoods by testifying about the president's cover-ups and illegal abuses of power.

Their honor, duty, bravery, self-sacrifice, and fidelity to the Constitution proved the quality of their personal character: the very highest.

John Bolton is not among the most courageous and honorable. Where was he when his country needed him the most?

I am reminded of the words of Dr. King: "The ultimate measure of a man is not where he stands in moments of comfort and convenience but where he stands in times of challenge and controversy."
