Speaker Nancy Pelosi and Sen. Chuck Schumer stormed out of a White House sitdown on Syria with President Trump after he called Pelosi “ a third-rate politician” and a Communist sympathizer in what the House speaker termed “a meltdown.”

“He was insulting, particularly to the speaker. She kept her cool completely. But he called her a third rate politician. He said that there are communists involved and you guys might like that,” Schumer said.

“This was not a dialogue. It was sort of a diatribe, a nasty diatribe not focused on the facts, particularly the fact of how to curtail ISIS, a terrorist organization that aims to hurt the United States,” he said.

Pelosi said Trump was shaken by an earlier House vote condemning his decision to pull troops from northern Syria.

‘What we witnessed on the part of the president was a meltdown, sad to say,” Pelosi said.

“I pray for the president all the time, and I tell him that — I pray for his safety and that of his family. Now, we have to pray for his health — because this was a very serious meltdown on the part of the president,” she said later at the Capitol.

Schumer said trouble started shortly after the start of the meeting — which also included top administration officials and leading lawmakers from both parties — with a discussion about securing ISIS prisoners.

“I told the president being from New York as he was [made him] particularly aware of the problems that terrorism that an organization like ISIS can create.,” Schumer told reporters outside the White House, while the meeting continued with other lawmakers remaining.

“And the fact that someone no less than General Mattis has said that ISIS has been enhanced, that the danger of ISIS is so much greater, worries all of us,” he said, referring to former defense secretary James Mattis, who resigned over Trump’s earlier call to bug out of Syria.

“I asked the president what his plan was to contain ISIS. He didn’t really have one. He said the Turks and the Syrians will guard the ISIS prisoners,” Schumer continued, saying he then asked if the administration had intelligence that the Turks and Syrians wouild fulfil that role.

“The secretary of defense was, thank God he was honest, he said we don’t have that evidence,” he continued, referring to Mike Esper.

The administration, he added, appeared to have no plan to contain the prisoners.

Schumer then said that Trump began personally insulting Pelosi, though the topic of impeachment never came up.

Majority Leader Steny Hoyer, who also bolted, said Trump would blame them for leaving.

“You’re gonna hear the president say we walked out. We were offended, deeply, by his treatment of the speaker. I have served with six presidents, never have I seen a president treat so disrespectfully a coequal branch,” Hoyer said.

House Minority Leader Kevin McCarthy blamed Pelosi, as did the White House.

“To storm out of a meeting, which I’ve watched time before, during other crisis, is really not — the ability of a speaker, or the style of how a Speaker should carry herself,” McCarthy told reporters.

“The president was measured, factual and decisive, while Speaker Pelosi’s decision to walk out was baffling, but not surprising. While Democratic leadership chose to storm out … everyone else in the meeting chose to stay in the room,” spokeswoman Stephanie Grisham told PBS.

Along with Trump and Esper, acting chief of staff Mick Mulvaney, White House counsel Pat Cipollone, and Treasury Secretary Steve Mnuchin attended the meeting.

Sens. Mitch McConnell (R-KY), Jim Inhofe (R-OK) and Jack Reed, (D-RI), were also there, among other senators. A bi-partisan group of House members also attended.
