Lt. Col. Alexander Vindman and his brother Yevgeny Vindman were involved in the impeachment investigation of President Donald Trump and raised concerns about the "toxic" climate created by senior White House national security officials who harassed women in the office and abused travel privileges.
Vindman cited intimidation and bullying from the White House for his decision to retire. He will retire at the lower rank of lieutenant colonel instead of colonel.
Alexander Vindman, an impeachment witness fired from the White House by Trump, will have an interim assignment before enrolling at a war college.
