WASHINGTON, DC - NOVEMBER 21: Fiona Hill, the National Security Council’s former senior director for Europe and Russia testifies before the House Intelligence Committee in the Longworth House Office Building on Capitol Hill November 21, 2019 in Washington, DC. The committee heard testimony during the fifth day of open hearings in the impeachment inquiry against U.S. President Donald Trump, whom House Democrats say held back U.S. military aid for Ukraine while demanding it investigate his political rivals and the unfounded conspiracy theory that Ukrainians, not Russians, were behind the 2016 computer hacking of the Democratic National Committee.
