One of the key witnesses in former President Donald Trump's first impeachment trial is suing Donald Trump Jr., Rudy Giuliani and several other White House officials over what he alleges was an intimidation campaign meant to smear him as "disloyal to the United States" and a "spy for a foreign country."
Lt. Col. Alexander Vindman became a star of the so-called "resistance" movement after reporting to House investigators that he thought a 2019 phone call between then-President Trump and Ukranian President Volodymyr Zelenskyy was "improper" and "inappropriate." On the call in question, Trump pushed Zelenskyy to investigate the Biden family's involvement in Ukraine, particularly his son Hunter Biden's seat on the board of Ukranian energy company Burisma.
