A key witness in Donald Trump’s first impeachment case has sued the former US president’s son, Donald Trump Jr; his personal lawyer, Rudy Giuliani; and other Trump allies, accusing them of conducting a “concerted campaign of unlawful intimidation”.
The 73-page lawsuit from retired United States Army officer Alexander Vindman, a former White House aide who testified during House of Representatives impeachment hearings in 2019, was filed on Wednesday in the US District Court in Washington, DC.
