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.

An administration lawyer said a Tennessee law barring some medical treatments for transgender youths is constitutional and urged the justices to say so.
