Former Vice President Joe Biden blasted President Donald Trump after Supreme Court Justice Ruth Bader Ginsburg died Thursday (Sept. 14).

While appearing on ABC’s This Week, the former VP said, “It’s sort of a slap in the face … I think it’s a blow to every woman that felt qualified to be on the Supreme Court because of it.”

Biden added that the new justice replacing Ginsburg is “one of the best and most progressive justices on the court, and not everybody will like her, but people feel compelled to find a judge like her and go to the polls.”

President Trump also responded. “Justice Ruth Bader Ginsburg joined the 5-4 liberals for the final time to uphold the Constitution, which should have been a green light for all other executive branch abuses of power!” he tweeted.

Biden, however, disagreed. “I thought Justice Ginsburg was one of the greatest justices who ever sat on the Supreme Court,” he said. “I thought she was a perfect choice. She was just one of the great justices who’s ever been on this Court.”

Meanwhile, Justice Anthony Kennedy delivered a missive to his colleagues from the White House. “The Constitution is sacred, and most of us have a duty to safeguard it, and protect the fidelity to it that we feel we owe to that sacred document,” he said. “So tonight is a sad day for the Court.”

Meanwhile, a second round of mixed reactions came after Justice Ginsburg’s death. Her son sent an Instagram post after her passing. “My love for her is limitless and I love her to the best of my ability.”

Ginsburg, 80, died at her home in New York City at 5:47 p.m. ET on Thursday. She was the oldest woman to sit on the Supreme Court.
