It shouldn’t have to be said, but Lt. Col. Alexander Vindman, the National Security Council officer testifying in the House impeachment proceeding, is a great American patriot. He is not a Ukrainian agent.

The line of attack against Vindman goes as follows: Somehow a Purple Heart recipient who spent two decades serving the United States in the military and then another as an Army foreign area officer secretly still holds primary allegiance to Ukraine, a nation he fled from as a Jewish refugee when he was 3 years old.
