President Donald Trump named three justices in his first term, establishing a conservative supermajority on the Supreme Court. And now, even without an imminent vacancy, Trump is positioned to push the court farther to the right.

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.

The court gave Trump major victories last year that helped clear away potential obstacles to his reelection, postponing his criminal trial in Washington, D.C., then affording immunity from prosecution for official actions. But Trump's first term was marked by significant defeats — as well as some wins — at the court.
