Several high-profile, right-leaning veterans slammed Lt. Col. Alexander Vindman after his public impeachment hearing, including his decision to wear his official military uniform.

Vindman, a decorated combat veteran working in the Trump administration, told the House Intelligence Committee on Tuesday that he found Trump's July 25 phone call with Ukrainian President Volodymyr Zelensky "inappropriate," echoing a whistleblower complaint that alleged the president improperly pressured Ukraine into investigating former Vice President Joe Biden.

Republicans on Capitol Hill and conservative media pundits have spent recent weeks discrediting Vindman, with some questioning the Ukrainian refugee's loyalty to the United States.

"I wish the left wouldn’t use his uniform to make him a saint. He’s an operative with an agenda," said Robert J. O'Neill, the Navy Seal who claims to have killed Osama bin Laden, after Vindman's testimony. Army Regulation 670-1 says, "when an invitation calls for business attire, the appropriate Army uniform is the service or dress uniform."

"Vindman is a disgrace to all who have served," Mark Geist, a Marine who fought the Battle of Benghazi in 2012, further blasted Vindman. "Transcript of his previous closed door testimony he clearly admits to undermining the [presidents] foreign policy, and now he has chairman Schiff advising him on how to answer questions."

During an exchange with Rep. Devin Nunes, Vindman asked the ranking member to address him by his military rank when the California Republican referred to him as "Mr. Vindman," saying, "It's Lieutenant Colonel Vindman, please."

"Correcting a civilian about how to be a addressed is a for sure way to make everyone in the military think you are a douche bag," Tim Kennedy, an MMA fighter and former Special Forces fighter, commented on the moment.

Democrats have condemned attacks on Vindman's patriotism, with Rep. Jim Himes saying, "That was designed exclusively to give the right-wing media an opportunity to attack your loyalties."
