An adviser to Vice President Mike Pence says she found a July phone call between President Donald Trump and the Ukraine leader "unusual" since it "involved discussion of what appeared to be a domestic political matter."
Jennifer Williams was at the witness table Tuesday as the House intelligence public hearing got underway. The House impeachment inquiry is looking into the Trump administration's interactions with Ukraine.
She listened to the July 25 call between Trump and Ukraine president Volodymyr Zelenskiy. She says that after the call, she provided an update in the vice president's daily briefing book indicating that the conversation had taken place.
Williams says she did not discuss the call with Pence or any of her colleagues in the office of the vice president or the National Security Council.
The House intelligence panel is holding public hearings into Trump's pressure on Ukraine to investigate his Democratic political rivals while also withholding aid to the Eastern European nation.

An adviser to Vice President Mike Pence says she was told that White House acting chief of staff Mick Mulvaney had directed that a hold on military aid to Ukraine should remain in place.
Jennifer Williams is testifying Tuesday in the House impeachment inquiry into the Trump administration's interactions with Ukraine.
Williams says she attended meetings earlier this year in which the hold on Ukraine security assistance was discussed.
She says representatives of the State and Defense departments advocated that the hold on the aid should be lifted, and that budget officials said that Mulvaney had directed that it remain in place.
Williams says she learned on Sept. 11 that the hold had been lifted. She says she's never learned what prompted that decision.
