Pence aide’s testimony renews focus on VP’s Ukraine role

A public appearance by an aide to Mike Pence before the House Intelligence Committee this week is drawing renewed attention to what the vice president knew about the events that sparked the House impeachment probe.

Investigators will hear from Jennifer Williams, a career foreign service officer detailed to Pence's office from the State Department. Aides to Pence insist he knew nothing about President Donald Trump’s efforts to pressure Ukrainians to investigate Democrats.

But they’re walking a thin political line in trying to make the case that Pence was out of the loop on questionable aspects of Trump’s Ukraine policy while also presenting Pence as an influential voice in prodding the president to release the military aid.
