US President Donald Trump confirmed Thursday that he was replacing his national security advisor Mike Waltz following a chat group leak, saying he planned to move him to the United Nations.In the first major cabinet shake-up of Trump’s new term, the president said Secretary of State Marco Rubio would now also serve as his “interim” national security advisor following Waltz’s departure.”I am pleased to announce that I will be nominating Mike Waltz to be the next United States Ambassador to the United Nations,” Trump said on Truth Social, confirming earlier reports that Waltz was being ousted.”Mike Waltz has worked hard to put our Nation’s Interests first. I know he will do the same in his new role.”Trump did not give a reason for the move but Waltz had been under pressure over the so-called “Signalgate” scandal since late March.The editor-in-chief of The Atlantic magazine revealed at the time that Waltz had mistakenly added him to a group chat about US strikes on Yemen’s Huthi rebels on the commercial messaging app Signal.Officials on the group laid out the attack plan, including the timings that US warplanes would take off to bomb targets, with the first texts barely half an hour before they launched.Despite intense media speculation that Trump would fire Waltz over the scandal, the president repeatedly offered his backing and the national security advisor appeared to have ridden out the storm.In the end, however, the 51-year-old former congressman from Florida lasted just over 100 days of Trump’s second term, which has so far been more stable in terms of personnel than his first.Democrats will now turn up the heat on Defense Secretary Pete Hegseth, who was the official who revealed the air strike details in advance, and who was also reported to have shared those details in a separate Signal group chat that included, among others, his spouse.”Now do Hegseth,” top Senate Democrat Chuck Schumer posted on X.Waltz’s new role will also require Senate confirmation, ensuring that Signalgate will stay in the headlines.There was no immediate confirmation of US media reports that Waltz’s deputy, Alex Wong, would also leave the National Security Council.US media had reported that Steve Witkoff, a real estate magnate whom Trump has picked to lead US talks with both Russia and Iran, is in contention to replace Waltz in the longer term.- ‘SCALP’ -Waltz was among a number of White House staff targeted by right-wing influencer and conspiracy theorist Laura Loomer, who met with Trump urging a purge.Loomer, who is known for claiming that the September 11, 2001, attacks were an inside job, is reported to have successfully pushed for the dismissal of several senior US security officials she deemed disloyal to the president.After news of Waltz’s ouster was reported Thursday, Loomer appeared to take credit in a post on X, saying: “SCALP.”Waltz showed no sign that he knew of his imminent departure when appearing early Wednesday on Fox News, where he hailed the new US minerals deal with Ukraine.Waltz was also present at Trump’s televised cabinet meeting on Wednesday when he lavished praise on the president.”We’ve had 100 days of your leadership with respect, with strength,” Waltz said. “It’s an honor to serve you in this administration.”A former special forces officer, Waltz was seen as a moderate voice in the Trump administration when he was appointed, but reportedly clashed with other officials over his hawkish stance against Russia and Iran.Trump has pushed for Ukraine to reach a quick ceasefire deal with Russia, while reopening negotiations with Iran over its nuclear program.The National Security Advisor’s role has been held in the past by some of the most high-profile officials in US history, including Henry Kissinger.But Waltz had been on borrowed time since Signalgate emerged as the first major scandal of the whirlwind start of Trump’s new term.On the text chain, Waltz sent real-time intelligence on the aftermath of an attack on the Huthis, writing that US forces had identified the target “walking into his girlfriend’s building and it’s now collapsed.”Hegseth revealed detailed timings of the US airstrikes on Yemen, putting him squarely in the Democrats’ crosshairs.

A federal judge in Texas ruled on Thursday that President Donald Trump’s use of an obscure wartime law to summarily deport alleged Venezuelan gang members was “unlawful.”District Judge Fernando Rodriguez, a Trump appointee, blocked any deportations from his southern Texas district of alleged members of the Tren de Aragua (TdA) gang using the 1798 Alien Enemies Act (AEA).Trump invoked the little-known AEA, which was last used to round up Japanese-American citizens during World War II, on March 15 and flew two planeloads of alleged TdA members to El Salvador’s notorious maximum security CECOT prison.In a proclamation, Trump said Tren de Aragua was engaged in “hostile actions” and “threatening an invasion or predatory incursion against the territory of the United States,” adding that Venezuela’s Nicolas Maduro was pulling the strings.The Supreme Court and several district courts have temporarily halted removals under the AEA citing a lack of due process, but Rodriguez is the first federal judge to find that its use is unlawful.”The president cannot summarily declare that a foreign nation or government has threatened or perpetrated an invasion or predatory incursion of the United States,” the judge said in his 36-page order.”Allowing the president to unilaterally define the conditions when he may invoke the AEA, and then summarily declare that those conditions exist, would remove all limitations to the executive branch’s authority under the AEA,” Rodriguez said.”The president’s invocation of the AEA… exceeds the scope of the statute and, as a result, is unlawful,” the judge said.The administration does not have the lawful authority, under the AEA, “to detain Venezuelan aliens, transfer them within the United States, or remove them from the country,” he added.- ‘Critically important decision’ -Lee Gelernt, an attorney with the American Civil Liberties Union (ACLU), which brought the lawsuit seeking to halt the removals, welcomed the ruling.”The court ruled the president can’t unilaterally declare an invasion of the United States and invoke a wartime authority during peacetime,” Gelernt said.”Congress never meant for this 18th-century wartime law to be used this way,” he said. “This is a critically important decision that prevents more people from being sent to the notorious CECOT prison.”While prohibiting deportations under the AEA, Rodriguez said the administration could proceed with removals under the Immigration and Nationality Act.Trump won the White House election last November in large part on promises to combat what he repeatedly claimed is an invasion of criminal migrants.Trump has sent troops to the Mexican border, imposed tariffs on Mexico and Canada for allegedly not doing enough to stop illegal crossings, and designated gangs like TdA and MS-13 as terrorist groups.Attorneys for several of the Venezuelans already deported have said their clients were targeted largely on the basis of their tattoos.In the most publicized case to date, Maryland resident Kilmar Abrego Garcia was deported to CECOT before the Trump administration admitted he was sent there due to an “administrative error.”
