Trump won't be back at the United Nations today, but world leaders speaking after him on day two of the General Assembly's gathering will be reckoning with the international order he's shaped.

In particularly, the leaders of both Iran, the nation Trump started a war with, and Ukraine, whose war with Russia Trump staked his 2024 campaign on ending, will feature in Wednesday's lineup of speakers.

The President of Iran, Masoud Pezeshkian, is slated to speak first, a day after Trump used his address to the body to threaten to "annihilate" his country and drive its people "into Hell" if Iranian leadership refused to strike a deal to end the war.

Around the same time Trump delivered those remarks, members of Trump's team, including Middle East envoys Steve Witkoff and Jared Kushner, held a snap meeting with the Iranian delegation, Trump later said. The President reported that the meeting went "very well," though Iran has since pushed back on claims that it dropped some preconditions for reopening the strait of Hormuz during those talks.

In a new legal filing in the case over a trio of new outlets barred entry to the White House, the Trump administration's Department of Justice repeatedly defended the president's ban by saying journalists were not entitled to access to the building.

"Access to the White House is a privilege, not a right," the filing stated.

The filing went on to assert that the three outlets – by publishing sensitive or classified information obtained through its reporting – constituted a national security threat, giving the president the right to ax their credentials.

Trump banned the three outlets – CNN, MS Now, and Politico – last Friday in a snap decision announced via social media. He branded the three outlets "fake news" and threatened future bans against other outlets could follow.

Early the following week, the three publications filed a joint lawsuit asking a federal judge to restore their access, alleging that the action was an illegal act of retaliation that violated their First Amendment rights. A president, they argued in their complaint, can't bar access to journalists based on reporting he doesn't like.

Since then, Trump has found himself in an escalating tit-for-tat with the press, which has responded to the ban with measures of solidarity. Several outlets have declined to publish any images or video of the president so long as the three outlets are denied access to the White House. And the members of Trump's standard TV pool – five channels, including CNN, who take turns traveling with the president, filming his daily activities, and distributing that footage – have ceased their duties.

The Trump administration is refusing to work with the newly appointed deputy head of the United Nations ⁠refugee agency, Reuters reported.

Tressa Rae Finerty, an American who took up the role of deputy high commissioner at UNHCR earlier ⁠this month, has taken leave as she seeks a waiver from the US government that would allow her to carry out aspects of her duties, ​according to seven diplomatic sources.

Her treatment by Washington, which previously considered cutting ‌ties with the agency, is seen ‌by several of the diplomats as a retaliatory response after UNHCR opted against Washington's preferred candidate, Simon Hankinson.

A State Department spokesperson said it ‌could not comment on pending legal issues. "We work with and through UNHCR when doing so advances US foreign policy interests," the spokesperson said.

Hello and welcome to the US politics live blog.

Donald Trump will meet with the Chinese president Xi Jinping later today, ahead of a three-day visit that will undoubtedly see artificial intelligence (AI) high on the agenda.

António Guterres, the UN secretary general, has called on the two countries to establish a dialogue on AI similar to the communication between the US and the Soviet Union during the cold war.

"Governments with the greatest AI capabilities have the greatest responsibilities to humanity, to establish channels for dialogue, transparency, trust and cooperation," Guterres said.

Tech executives including Jeff Bezos of Amazon, Sundar Pichai of Alphabet, Sam Altman of ⁠OpenAI, Tim Cook of Apple, Elon Musk ​of ​Tesla, Mark Zuckerberg of Meta and Jensen Huang ​of Nvidia will reportedly ​attend a ⁠state dinner at the White House on Thursday evening.

It comes as two leading progressive US lawmakers, senator Bernie Sanders and representative Greg Casar, were due to unveil legislation later today that would ban artificial superintelligence and create a federal agency to oversee advanced AI.

The bill, provided first to the Associated Press, would also pause advanced AI development until guidelines are implemented while creating the Department of Artificial Intelligence. Multiple employees at leading AI companies are endorsing the bill.

"It doesn't take a genius to say, 'slow it down,'" Sanders said in an interview with AP. "Do we really want to develop a super intelligence that when it becomes smarter than human beings could act independently of human control? I don't think we do."

Congress has so far done little to rein in the AI industry even as some of its most prominent leaders warn about potentially catastrophic risks.

Xi departed Beijing on Wednesday, state media said, heading to Joint Base Andrews, Maryland, where he will be met by Trump on the tarmac.

"President Xi Jinping left Beijing by special plane for a state visit to the United States" accompanied by his wife Peng Liyuan, his right-hand man Cai Qi, and foreign minister Wang Yi, among others, state broadcaster CCTV said.
