(FILES) A view of the US Supreme Court in Washington, DC, on January 21, 2026. US President Donald Trump will personally attend Supreme Court oral arguments April 1st in his bid to end the longstanding policy of birthright citizenship, in an extraordinary move that may be without historical precedent. The White House confirmed Trump's intention to attend the hearing at 10:00 am (1400 GMT) in its daily guidance on the president's schedule. (Photo by Brendan SMIALOWSKI / AFP via Getty Images)
