The highlight of Tuesday’s proceedings was the testimony of Lt. Col. Alexander Vindman, the director of European affairs at the National Security Council, who testified that President Donald Trump had demonstrated improper conduct when he mentioned political investigations during a July 25 phone call with the president of Ukraine.
The committee also heard testimony from Jennifer Williams, an advisor to Vice President Mike Pence, who also listened in on on the July 25 call. Williams testified that she found the call “unusual” because it involved a “domestic political matter.” She said she did not flag her concerns at the time, however, because her direct supervisor was also on the call.
