President Donald Trumpattacked the judges whoblocked his tariffs, a ruling latertemporarily pausedon appeal, and blamed the Federalist Society, a conservative legal group for giving him badadvice during his first termon judicial picks. In alengthy social media postMay 29, part of apattern of Trump lashing out at a judiciarythat has ruled against major pieces of his second-term agenda, the president directed his ire at the three-judge panel of the U.S. Court of International Trade. The panel is the same one that invalidated his use of an emergency-powers law to implement tariffs. "Where do these initial three Judges come from?" Trump asked. "How is it possible for them to have potentially done such damage to the United States of America?" Trump and his allies have led anintense pressure campaignon the judiciary for blocking some of his unprecedented and aggressive uses of executive power. Trump routinely slams judges on social media and has threatened their impeachment. This time Trump also is turning his anger toward a pillar of the conservative legal establishment. He singled out the Federalist Society, whichduring Trump's first termadvised him on judicial nominations, including eventualSupreme Courtpicks Neil Gorsuch, Brett Kavanaugh and Amy Coney Barrett.

"I did so, openly and freely." Trump then criticized Leonard Leo, the Federalist Society's former executive vice president and current co-chairman of the board, calling him a "bad person." The group did not immediately respond to a request for comment. "I am so disappointed in The Federalist Society because of the bad advice they gave me on numerous judicial nominations," Trump wrote. Trump turned to a close ally for one of his latest judicial picks,nominating Justice Department official Emil Bove, his former personal attorney. (This story has been updated with more information.)
