In the August complaint, Lt. Col Yevgeny Vindman alleges he faced retaliation from Trump and White House officials after raising concerns about the presidents pressure on Ukrainian officials to investigate Democrat Joe Bidens family the heart of the Democrats impeachment inquiry.
Both Vindmans worked for the National Security Council in the White House and were reassigned to the Army after the Senate voted to acquit Trump in his impeachment trial.
If the White House refuses to cooperate fully including by denying requests for documents or for interviews with White House officials we will have no other choice but to infer that any such actions were retaliatory, the Democrats wrote.
Mark Zaid, a lawyer for Yevgeny Vindman, confirmed the existence of the complaint and said it states that that senior White House officials, to include the president, retaliated against him for performing his duty as an attorney and soldier. The White House did not immediately comment on the allegations.
The allegations are wide-ranging, including his apprehension about the pressure on Ukraine and the behavior of OBrien, who was then the assistant to the president for national security affairs.
