Trump admin live updates: Judge blocks IRS sharing taxpayer data with ICE

The Supreme Court on Monday said it would consider the Trump administration's bid to reinstate a policy of turning back asylum seekers at border crossings, in effect preventing them from applying for protection inside the United States.

The policy, which lower courts have declared unlawful and blocked from enforcement, is a major component of President Donald Trump's stringent approach to immigration and plans to limit border surges and overcrowding at points of entry.

The case will likely be scheduled for oral argument in spring 2026 and decided by the end of June.

Federal law requires the government to allow any migrant "who arrives in the U.S." to apply for asylum and receive an interview with an immigration officer.

The Trump administration argues that migrants stopped on the Mexican side of the southern border have not "arrived in the U.S." and therefore have no right to seek legal protection on American soil. Immigrant advocacy groups challenging the Trump policy insist that blocking asylum seekers is plainly against the law.

President Donald Trump suggested Sunday that he plans to meet with New York City's mayor-elect Zohran Mamdani.

"The mayor of New York, I will say, would like to meet with us. And we'll work something out, but he would like to come to Washington and meet and we'll work something out," Trump said to reporters on the tarmac in Florida before traveling back to Washington.

"We want to see everything work out well for New York," he added.

The comments come after Trump railed against Mamdani during the election, calling him a "communist lunatic," and threatened to withhold federal funding to New York City if Mamdani won. Mamdani, in his victory speech, called out Trump directly and later told "Good Morning America" he would not be "intimidated" by the president.

In an interview with WABC over the weekend, Mamdani reiterated a willingness to work with Trump if their values are aligned on making life more affordable for New Yorkers -- but also indicated he'd push back on Trump, too, if need be.

"I look forward to having a conversation with President Trump, because it's one where I'll make clear if he wants to work together to deliver on his campaign promises of cheaper groceries or a lower cost of living, I am there and I am ready to go. But if he wants to talk about pursuing a campaign agenda that comes at the expense of New Yorkers, that is something that I will fight," Mamdani said.

President Donald Trump and his administration filed on Sunday a motion to stay an order from a federal judge who had earlier this month ruled the president "exceeded" his authority by sending the National Guard to Oregon.

"The President was well within his discretion to consider months-long unrest in Portland, as well as the potential for continuing unrest over the foreseeable future," the White House wrote in its motion, which was filed Sunday on in the 9th Circuit Court.

District Judge Karin Immergut ruled in early November that Trump "exceeded the President's authority" when he sent federalized National Guard troops into Portland.

The administration on Sunday argued that the court should place an administrative stay on the part of Immergut’s order that required a defederlization of those Guardsman.

The administration argued that the court had "downplayed the dangerous conditions" at a federal Immigration and Customs Enforcement facility, where public demonstrations were ongoing throughout the summer.

"The court acknowledged large-scale violent protests in June, but treated them as irrelevant to the President's determination just a few months later," the Sunday filing said. "And while the court attempted to paint a picture of sharp decline in violent activity since then, the record shows that violence and threats of violence recurred more-or-less continuously."

Officials in Portland have "publicly opposed the use of excessive force by federal agents and the broader enforcement approach of the Trump Administration," according to the city's official website.
