During an Oval Office executive signing, President Donald Trump spoke about the ongoing funding bill that has stalled in the Senate.

Trump admonished the Democrats for not signing on and warned of a shutdown.

"I think you could very well end up with a closed, closed country for a period of time, and we'll take care of the military. We'll take care of Social Security. We'll take care of the things," Trump said.

The Senate on Friday confirmed Mike Waltz to be the Ambassador to the United Nations by a vote of 47-43 – just days before the UN General Assembly is scheduled to start in New York.

Sens. Mark Kelly of Arizona, John Fetterman of Pennsylvania and Jeanne Shaheen of New Hampshire were the only Democrats to support the confirmation. Kentucky Sen. Rand Paul was the only Republican to vote no.

Walz previously served as national security adviser for the president, however, he came under fire in the spring for inadvertently adding a reporter to a Signal chat with top Trump officials discussing a U.S. military strike on Houthi rebels in Yemen.

Trump announced in May that Walz was leaving his adviser position and nominated to be the U.N. ambassador role that was originally offered to U.S. Rep. Elise Stefanik. Her nomination was withdrawn over concerns about the House's slim majority.

Trump said in a social media post Friday he will meet with Turkish President Erdoğan at the White House on Thursday, Sept. 25, as they work on trade deals, including for Boeing aircraft and military jets.

Trump said he’s “always had a very good relationship” with Erdoğan.

This announcement comes just a few days after Trump conditioned his threat of secondary sanctions on Russia on NATO allies agreeing to forgo purchasing Russian oil. Turkey is one of the largest importers of Russian oil.

President Donald Trump, following a "very productive" phone call with Chinese President Xi, said in a social media post that he would meet with the Chinese leader at the APEC summit in South Korea that starts next month.

Trump added that he will travel to China "in the early part of next year." Trump said Xi would visit the U.S. himself "at an appropriate time."

The president did not announce major updates about a potential deal on TikTok, only saying the two "made progress" on that topic and others, including trade.
