President Donald Trump's sweeping assertions of executive power during his first weeks back in office appear headed toward U.S. Supreme Court showdowns, but it remains an open question whether or how much the justices might act to check his authority.

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.

President Donald Trump’s administration is switching positions in a major Supreme Court case on transgender rights, backing away from the Biden administration’s opposition to Tennessee’s ban on gender-affirming care for minors.
