"You're going to hear the president say we walked out. We were offended deeply by his treatment of the speaker of the House of Representatives. The president in my view has created a crisis in the Middle East. A crisis that undermines the world's confidence in America. This crisis required a rational, reasonable discussion between those of us elected by the American people to set policy. Unfortunately, the meeting deteriorated into a diatribe, as Leader Schumer has said, and very offensive accusations being made by the president of the United States. I have served with six presidents. I have been in many, many, many meetings like this. Never have I seen a president treat so disrespectfully a co-equal branch of the government of the United States. 

Why it matters: Pelosi suggested that Trump was "shaken up" after the House voted overwhelmingly and in bipartisan fashion to condemn his decision to move U.S. troops out of northern Syria. Democrats and Republicans alike, including those like Sen. Lindsey Graham who have been among Trump's most loyal defenders, have lobbed intense criticism at the president over allegations that he has abandoned the Kurds.

• Trump defended the decision at a press conference on Wednesday, claiming that the Kurds — who the U.S. allied with in the fight against ISIS — are "not angels," and that Russia and the Syrian government will protect them from Turkey's military offensive.

Between the lines: This was the first face-to-face meeting between Trump and Pelosi since House Democrats launched a formal impeachment inquiry. The Washington Post notes that Trump has previously maintained a veneer of respect toward Pelosi because she acted as a buffer against impeachment for so long.

According to a Democratic source, Trump started the meeting with a "bombastic" monologue that included bragging about his letter to letter to Turkish President Recep Tayyip Erdoğan, claiming he had "agreed" to take part in the meeting when it was, in fact, called by the White House. Trump also suggested that that there are communists in Syria and that Democrats would like that.

• At one point, Trump told Pelosi: "I hate ISIS more than you do." Schumer later asked about his plan for Syria, and Trump said: "Our plan is to keep the American people safe." Pelosi responded: "That's not a plan. That's a goal."   
• Trump tried to blame President Obama for the situation in Syria and called Pelosi a "third-grade politician."
• Hoyer responded, "This is not useful," before he and Pelosi stood and left the meeting. As they left, Trump stated, "Goodbye, we'll see you at the polls." Schumer left shortly after.

The other side: House Minority Leader Kevin McCarthy (R-Calif.) told reporters that Pelosi "stormed out of the meeting" and sought to make it "unproductive" and "political" in a moment of crisis.

• The White House said in a statement: "The President was measured, factual and decisive, while Speaker Pelosi's decision to walk out was baffling. ... While Democratic leadership chose to storm out and get in front of the cameras to whine, everyone else in the meeting chose to stay in the room and work on behalf of this country."

The big picture: AP notes that the House debate on the resolution was "extraordinary for the intensity of lawmakers’ opinions." In the Senate, Sens. Lindsey Graham (R-S.C.) and Chris Van Hollen (D-Md.) plan to introduce a bill as early as Thursday that would introduce crippling sanctions against Turkey for its military operation.

• Trump has already authorized sanctions against some Turkish officials, but he made clear on Wednesday that he does not regret the decision to withdraw troops from northern Syria.
• "Our soldiers are not in harm's way, as they shouldn't be, as two countries fight over land that has nothing to do with us," Trump said at a press conference with Italian President Sergio Mattarella. "And the Kurds are much safer now. The Kurds know how to fight, and as I said, they're not angels."

"[O]ur soldiers are not in harm's way, as they shouldn't be, as two countries fight over land that has nothing to do with us. And the Kurds are much safer right now. But the Kurds know how to fight, and as I said, they're not angels. They're not angels. ... Syria probably will have a partner of Russia, whoever they may have. I wish them all a lot of luck."

Driving the news: Trump has sent a delegation led by Vice President Mike Pence and Secretary of State Mike Pompeo to negotiate with Turkish President Recep Tayyip Erdogan, who said on Wednesday that he would "never declare a ceasefire," which Trump disputed. On Monday, Trump authorized sanctions punishing Turkey for its military operation.

• Erdogan views the primarily-Kurdish Syrian Democratic Forces (SDF) as an extension of the Kurdistan Workers Party, a militant group designated as a terrorist organization by both the U.S. and Turkey.
• The SDF, which is also guarding detention camps with thousands of captured ISIS fighters and families, has struck a deal with Syrian dictator Bashar al-Assad to protect the border from Turkey's military assault. This has allowed Russian forces who back Assad to move into areas that had been under Kurdish control for 7 years.

The big picture: During the fight against ISIS, the SDF — trained and armed by the U.S. — lost more than 10,000 troops. Republicans and Democrats have condemned Trump's decision to abandon the Kurds. Sen. Mitt Romney (R-Utah) called it a "very dark moment in American history," while Sen. Lindsey Graham (R-S.C.) said that Trump will have "blood on his hands" if ISIS returns.

"If the President did say that Turkey's invasion is no concern to us I find that to be an outstanding—an astonishing statement which I completely and totally reject. ... If you're not concerned about Turkey going into Syria why did you sanction Turkey?"
