A former adviser to U.S.
Secretary of State Mike Pompeo who abruptly resigned last week spoke on Wednesday to an impeachment inquiry into allegations President
Donald Trump pursued political interests in his dealings with Ukraine.
Former Pompeo adviser Michael McKinley, the latest senior administration official to give closed-door testimony to the Democratic-led inquiry, faced questions from investigators as
Republicans in
Congress stepped up attacks on a process that could end in Trump's impeachment by the House of Representatives before the end of the year.
Lawmakers are examining whether Trump improperly pressured
Ukraine to launch an investigation of former Vice President
Joe Biden, a top political rival and leading candidate for the
Democratic 2020 presidential nomination.
