A friend emailed this to me:
"According to the Merriam-Webster Dictionary, a traitor is “one who betrays another's trust or is false to an obligation or duty.” Regardless of what criminal charges the Justice Department may or may not bring against Donald Trump and those around him, it is clear from a political standpoint — based on what we have seen in the Congressional hearings to date — that we can righteously call Donald Trump, his allies, and those who support him traitors.
They have betrayed the United States of America. Those in Congress who continue to support him should resign in disgrace. Whether they do or do not, their dishonor will live in history."
