Trump tried to extort Zelenskyy and was impeached – now he may succeed

The Ukrainian president is expected at the White House on Friday to sign a multimillion-dollar minerals deal with echoes of a notorious 2019 phone call

Alexander Vindman remembers the phone call - and what he did next. Serving on the national security council (NSC), he went to see his twin brother, who was the council's senior ethics official, closed the door and told him: Eugene, if what I'm about to tell you ever becomes public, Donald Trump will be impeached."

Vindman had set up a call between Trump and Ukraine's new president, Volodymyr Zelenskyy, in July 2019. He heard the US president attempt to leverage US military aid to the country in return for Zelenskyy launching an investigation into Joe Biden's son, Hunter, over his position at a Ukrainian gas company.
