The Washington Examiner states:
Trump has accused Vindman of being a “Never Trumper,” a charge the NSC official denied on Tuesday.
“I would call myself Never Partisan,” Vindman told the House Intelligence Committee.
Vindman, a 44-year-old Army combat veteran who received a Purple Heart for injuries sustained during an IED explosion in Iraq in October 2004, initially registered as a Democrat in New York in 1994. He was listed as a Democrat at least as recently as 2009, according to public records. In 2012, Vindman registered to vote in Washington, D.C., but did not declare a party.
I could not find this info about Vindman's (former) overt political affiliation stated anywhere else though. So, is it true?
