U.S. Supreme Court Justice Ruth Bader Ginsburg steered clear of presidential politics Thursday in her first public appearance in Washington since her criticisms of Republican candidate Donald Trump made headlines last month.

Speaking to Duke University students and alumni Thursday night at the offices of the Jones Day law firm, Ginsburg spoke about last term’s decisions and the death of her close friend Justice Antonin Scalia in February. His death, she said, was “by far the most momentous occurrence of the term.”
