Trump Jr. said in the session, which was not held under oath, that he was looking to assess Clinton's "fitness" for office. The testimony was part of the committee's ongoing investigation into Russian meddling in the election.

The statute prohibits the falsifying or covering up of any material fact to Congress, and pertains to "procurement of property or services."

Trump Jr. has become a key figure in the various Russia probes since the meeting was first reported. He has denied that he received any damaging information about Clinton after taking the meeting.
