US President Donald Trump on Wednesday defended as "strategically brilliant" his decision to pull US troops out of Syria as the House of Representatives overwhelmingly condemned the move in a rare bipartisan rebuke.

A total of 129 members of Trump's Republican Party joined Democrats as the House denounced the withdrawal of US troops from northern Syria in a 354-60 vote.

The joint resolution called on Turkish President Recep Tayyip Erdogan to immediately halt military operations against Kurdish militants in Syria.

In a sign of Trump's deteriorating relationship with Congress, where the House is conducting an impeachment inquiry, Democratic House Speaker Nancy Pelosi and Senate minority leader Charles Schumer walked out of what they said was an acrimonious White House meeting with Trump.

Schumer said Trump had called Pelosi a "third-rate politician" while the speaker said the president had experienced a "meltdown."

Trump then took to Twitter, accusing Pelosi of having her own "meltdown," while adding that the Democratic leader "needs help fast!"

"There is either something wrong with her 'upstairs,' or she just plain doesn't like our great Country," the president wrote.

Faced with mounting bipartisan criticism in Washington over the abrupt pullout of US forces from Syria, Trump denied he had given Erdogan a "green light" to launch operations against the Kurds.

"President Erdogan's decision didn't surprise me because he's wanted to do that for a long time," Trump told reporters earlier in the day at the White House. "He's been building up troops on the border with Syria for a long time."

The US president disparaged the Kurdish allies he abandoned in the face of the Turkish offensive, saying they were "not angels," as well as his Republican critics at home.

"I didn't give him a green light," Trump said of a telephone conversation he held with Erdogan prior to the Turkish incursion. "Just the opposite of a green light."

In the letter dated October 9, Trump told Erdogan "you don't want to be responsible for slaughtering thousands" of people and urged him not to be a "tough guy" or a "fool."
