The House impeachment inquiry interviewed
Mike Pence special adviser Jennifer Williams, a specialist on European and
Russian affairs who listened in on Donald Trump’s “quid pro quo” call with Volodymyr Zelensky of
Ukraine, after issuing a subpoena commanding her to appear, circumventing
White House objections to her giving testimony.The president has meanwhile angrily denounced as “degenerate” a
Washington Post report that he asked his attorney general,
William Barr, to declare publicly that the Zelensky call of 25 July contained no illegality, only for Mr Barr to decline.
