Retired Army Lt. Col. Alexander Vindman is suing Donald Trump Jr., Rudy Giuliani and two former White House staffers for allegedly seeking to prevent and later punish him for testifying in the first impeachment of Donald Trump.

In his civil lawsuit filed Wednesday in federal court in Washington, D.C., Vindman accuses the defendants of engaging in an “intentional, concerted campaign of unlawful intimidation and retaliation” against him for testifying before Congress in 2019.

Vindman, an Iraq war veteran who served as a Ukraine expert on the National Security Council in the Trump White House, emerged as a key witness in the impeachment proceedings against then-President Trump. He testified about a phone call Trump had with Ukraine’s president — a call that was central to the allegations against Trump.
