WASHINGTON — Donald J. Trump described Justice Ruth Bader Ginsburg on Tuesday as a “disgrace” to the Supreme Court after she expanded on the criticism of the presumptive Republican presidential nominee that she first voiced last week.

In an interview published online by CNN on Tuesday, Justice Ginsburg called Mr. Trump “a faker” who has “an ego” and has been treated too gently by the press. She said Mr. Trump “says whatever comes into his head at the moment” and has no consistency in his thinking.

Justice Ginsburg’s comments came just days after she said she could not imagine the impact of a Trump presidency. “For the country, it could be four years. For the court, it could be — I don’t even want to contemplate that,” Justice Ginsburg said in an interview on Friday with The New York Times.

In an interview with The Associated Press, she said something similar.
