Perry was one of nine different officials from the White House, the State Department, and the Cabinet - in just three days this week - who defied subpoenas for their testimony.
Democrats said if the top officials from the Trump Administration had only testimony which would benefit the President, then they would probably stop at nothing to tell the world that message.
'This will only further add to the body of evidence of a potential obstruction of Congress charge against the President," said Rep. Adam Schiff (D-CA), who is leading the impeachment proceedings at this point in the House.
On Wednesday, only one of four officials showed up to testify; that was David Hale, a top State Department official.
"We wish others would show the same courage and dedication to the law," Schiff told reporters.
Meanwhile, Democrats began to mock GOP lawmakers who had furiously complained about the closed door depositions conducted in recent weeks, arguing that Republicans were saying little about the hundreds and hundreds of pages of testimony released this week.
Republicans brushed aside such criticism, as they argue that Democrats are wasting the time of the American people.
"This is nothing but a show trial in the U.S. House of Representatives," said Sen. David Perdue (R-GA).
"They're trying to undo the free and open election of 2016 that elected Donald Trump to be President of the United States," Perdue added.
