While it was once rare for an administration to change its position in cases before the high court, Trump did so in his first term and has signaled he will do it again.

President Donald Trump's administration told the U.S. Supreme Court on Friday that Tennessee's Republican-backed ban on gender-affirming medical care for transgender minors is not unlawful, reversing the position taken by the government under his Democratic predecessor Joe Biden.

The A.C.L.U. filed a lawsuit after the president’s administration stopped issuing passports that reflect the gender identity of transgender and nonbinary people.
