A judge on Tuesday dismissed a lawsuit that accused Donald Trump’s oldest son and other Trump allies of an intimidation and defamation campaign targeting a retired Army lieutenant colonel who served as a key witness in the former president’s first impeachment case. Alexander Vindman testified during 2019 impeachment proceedings about a phone call in which Trump pressed his Ukraine counterpart to investigate Democratic rival Joe Biden and his son, Hunter. Trump was impeached by the House but acquitted by the Senate in February 2020.
