President Donald Trump attacked House Speaker Nancy Pelosi (D-CA) from the White House on Tuesday.
As impeachment testimony was underway in the House, Trump told reporters in a Cabinet meeting that Pelosi is "grossly incompetent."
The president also said that Republicans are "killing it" in the impeachment hearings.
But Trump took a shot at Lt. Col. Alexander Vindman, an expert on Ukraine who was testifying at the time.
"I don't know him. ... I never saw the man," he said. "I understand now he wears his uniform when he goes in. No, I don't know Vindman at all. What I do know is that even he said that the transcript was correct."
According to reports, the president went on to insist that a recent surprise trip to Walter Reed medical center was "very routine."
