Washington (CNN) Congressional Democratic leaders offered a remarkable readout of a meeting with President Donald Trump on Wednesday, saying that the President called House Speaker Nancy Pelosi a "third-rate politician" in what they described as a "meltdown."

"He was insulting, particularly to the speaker. She kept her cool completely, but he called her a third-rate politician," Senate Democratic leader Chuck Schumer told reporters, describing the interaction. "This was not a dialogue, it was sort of a diatribe. A nasty diatribe, not focused on the facts."

Pelosi added, "What we witnessed on the part of the President was a meltdown, sad to say."

The Democratic leaders were at the White House for a meeting on Syria, which came shortly after the House overwhelmingly passed a bipartisan vote on a resolution opposing the Trump administration's troop withdrawal.

Speaking to reporters after the meeting, the top congressional Democrats said that they walked out. Schumer said they did so "when he started calling Speaker Pelosi a third-rate politician."
