The U.S. Supreme Court early Saturday halted the Trump administration’s use of the Alien Enemies Act to deport migrants who are being detained in Texas, The Hill reports. The emergency order temporarily blocks deportations until the court resolves an emergency appeal from the American Civil Liberties Union. On Friday, the group asked a number of courts to intervene alleging that deportations were actively underway. The Justice Department disputed those claims. The high court decision comes a few days after U.S. District Judge James Boasberg found "probable cause" to hold administration officials in contempt for deporting accused Venezuelan gang members to El Salvador in March after he ordered the planes to turn around, Bloomberg Law reports. On Friday, the U.S. Court of Appeals for the D.C. Circuit halted those contempt proceedings to give it sufficient opportunity to consider the government’s appeal. The Hill reports on that development.

The U.S. Supreme Court will hear oral arguments on President Donald Trump's effort to end birthright citizenship on May 15. The government is seeking to enforce the president’s executive order ending the guarantee of citizenship to almost everyone born in the United States. The court left in place orders by three federal judges, which had prohibited the government from enforcing the executive order anywhere in the country, until it rules on the matter.

The man charged with attempting to murder U.S. Supreme Court Justice Brett Kavanaugh in 2022 pleaded guilty Tuesday in federal court after previously entering a not guilty plea, Axios reports. Nicholas John Roske admitted to one count of attempting to assassinate a U.S. justice without reaching a plea agreement with federal prosecutors and could face life in prison. His attorneys wrote in a court filing last week that Roske told law enforcement he had traveled to Maryland with the intent to kill Kavanaugh and then himself. U.S. District Judge Deborah Boardman scheduled a sentencing hearing for Oct. 3.

After a prosecutor acknowledged that a Maryland man was wrongly deported to El Salvador due to an "administrative error," the Trump administration was ordered to return him to the United States. On Friday, U.S. District Judge Paula Xinis directed the administration return Kilmar Abrego Garcia in response to a lawsuit filed by the man and his family. Today, U.S. Supreme Court Chief Justice John Roberts temporarily paused the compliance deadline, which was to take effect at midnight tonight, The Hill reports. Roberts agreed to hold the deadline until the high court can resolve the administration’s emergency request to lift the lower court order. The administration argues that Garcia has ties to the MS-13 gang. A judge previously ruled he should not be deported to El Salvador due to concerns he would face harm there. His family says he does not have gang connections.

The U.S. Supreme Court unanimously overturned a lower court ruling today, finding the Food and Drug Administration (FDA) acted lawfully in blocking two vaping companies from marketing fruity and dessert-flavored liquids for their electronic nicotine products. The decision rejected an earlier ruling from the U.S. Court of Appeals, The Hill reports. In an opinion written by Justice Samuel Alito, the court upheld the FDA’s approach, stating that the agency had made its decisions based on whether the products appealed to young people. The FDA has authorized the sale of only 34 electronic cigarette products, with all but one being tobacco-flavored, a flavor less popular among youth. In 2020, two companies petitioned the FDA to sell flavors such as sour grape and pink lemonade but the agency rejected those applications. The companies sued and the 5th U.S. Circuit Court of Appeals found in their favor. The FDA then appealed to the Supreme Court.

The U.S. Supreme Court upheld the Biden administration’s regulation of "ghost guns" in a 7-2 decision, rejecting a challenge from gun rights groups and manufacturers. The regulation, enforced by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), requires ghost guns, sold as do-it-yourself kits, to be treated like other firearms, The Hill reports. “Future cases may present other and more difficult questions about ATF’s regulations. But we take cases as they come and today resolve only the question posed to us,” Justice Neil Gorsuch wrote for the majority. Justices Clarence Thomas and Samuel Alito dissented separately, saying they would have invalidated the rule. In 2022, the ATF began regulating ghost guns as any other firearm, subjecting the devices to requirements such as serial numbers and background checks.

The Trump administration has asked the U.S. Supreme Court to allow the firing of thousands of workers at six federal agencies after a judge ordered that they be reinstated. Bloomberg Law reports that the U.S. Justice Department (DOJ) filed an emergency application today. The case involves 16,000 fired workers who had probationary status, meaning they had been in their roles for no more than two years. Departments impacted include Agriculture, Defense, Energy, Interior, Treasury and Veterans Affairs. DOJ also asked the court for permission to keep the reinstated employees on paid administrative leave instead of taking steps to restore them to full active duty while the litigation process proceeds.

U.S. Supreme Court Justice Elena Kagan defended the right of people to criticize the court's decisions and whether the justices are doing their jobs while speaking last month at an event for Princeton University, Bloomberg Law reports. Kagan said the public is entitled to express views about whether the court is doing its job properly. "In the end, the results matter, people are absolutely entitled to make judgments about the court based on the results that the court is reaching and the reasons that the court is giving for those results," she said.

The Trump administration has asked the U.S. Supreme Court to weigh in on three preliminary injunctions issued by federal district judges in Seattle, Maryland and Massachusetts, which bar the government from implementing the president’s executive order ending birthright citizenship in certain situations. The court is giving the other side until April 4 to respond, according to SCOTUSblog. The executive order made it official government policy that children born to mothers not legally in the country or here temporarily, and whose fathers are not citizens or lawful permanent residents at the time of the birth, would not automatically become citizens of the country.

U.S. Supreme Court Chief Justice John Roberts issued a rare public statement Tuesday after President Donald Trump's call to impeach a federal judge who ruled against his administration in a high-profile deportation case. “For more than two centuries, it has been established that impeachment is not an appropriate response to disagreement concerning a judicial decision. The normal appellate review process exists for that purpose,” Roberts said. In his 2024 year-end report, Roberts reiterated concerns about judges’ safety and condemned elected officials who intimidate judges or defy court rulings. The Hill has more.
