President-elect Donald Trump, who moved the U.S. Supreme Court dramatically rightward in his first term, may get a chance to rejuvenate its 6-3 conservative majority by replacing some or all of its three most senior conservatives with younger jurists - and perhaps even expand it if a liberal justice leaves.

Some liberals called for Justice Sonia Sotomayor to retire before Donald Trump returns to the White House. But Democrats would struggle to confirm a replacement.
