Former Vice President Joe Biden on Friday called for the Democrat primary debate audience in New Hampshire to give a standing ovation for Lt. Col. Alexander Vindman hours after he was removed from the National Security Council by the White House.

“Col. Vindman got thrown out of the White House today, walked out,” Biden said. President Trump “should have been pinning a medal on Vindman and not on Rush Limbaugh.”

“I think we should call stand and give Col. Vindman a show of how much we support him,” the former vice president added. “Stand up and clap for Vindman!”

Earlier Friday, Vindman, the NSC’s Ukraine expert, was escorted out of the White House and told his services were no longer needed. CNN reported that Vindman’s twin brother, Yevgeny, an ethics attorney on the NSC, was also terminated and escorted from the White House. Vindman listened in on the July 25 telephone between President Trump and Ukrainian and was a key witness in the House Democrats’ partisan impeachment inquiry.

Testifying before the House Intelligence Committee, Vindman criticized the Trump-Zelensky call and alleged that he did not know the identity of the whistleblower, whose complaint sparked the impeachment investigation.
