The House Intelligence Committee will hear testimony from four witnesses on Tuesday as the second week of public impeachment hearings gets underway.
The first two witnesses -- Alexander Vindman and Jennifer Williams -- will testify Tuesday morning on Capitol Hill. Williams is an aide to Vice President Mike Pence, and Vindman is an expert on Ukraine on the National Security Council who reported concerns about President Trump's July call with the leader of Ukraine.
In the afternoon, the committee will hear testimony from Kurt Volker and Tim Morrison. Volker, the former special envoy to Ukraine, was heavily involved in the campaign to pressure Ukraine to announce investigations into Mr. Trump's political rivals. Morrison told lawmakers in earlier closed-door testimony that he was concerned that details of the president's July call would become public, but didn't think "anything illegal was discussed" in the conversation.
The first round of hearings is set to get underway at 9 a.m. ET, with the afternoon session expected to begin around 3 p.m., depending on the timing of votes on the House floor.
