Supreme Court Justice regrets 'ill-advised' criticism of Trump
US Supreme Court Justice Ruth Bader Ginsburg has said she regrets her "ill-advised" public criticism of Donald Trump.
Ms Ginsburg said that judges should avoid commenting on a candidate for public office and promised to be more circumspect in the future.
She said last week that she did not want to think about the prospect of the Republican winning the presidency over Democrat Hillary Clinton.
She escalated her criticism in subsequent media interviews, including calling Mr Trump a "faker" who "really has an ego".
She came under attack for her comments in recent days, leading to Thursday's statement.
Mr Trump tweeted that the 83-year-old justice was an embarrassment for making "very dumb political statements about me. Her mind is shot - resign!".
Ms Ginsburg was appointed to the court in 1993 by his opponent's husband, former president Bill Clinton.
Other Republicans have chimed in, including Senate majority leader Mitch McConnell of Kentucky, who called Ms Ginsburg's remarks "totally inappropriate".
"She oughta stay out of it," said Senate Judiciary Committee chairman Chuck Grassley. "It hurts the court when she does that."
