US President Donald Trump has said that he thinks the 2020 US presidential election will end up in the Supreme Court, suggesting that it is important to immediately fill the vacancy left after Justice Ruth Bader Ginsburg’s death.

“I think this will end up in the Supreme Court,” Trump told reporters. “And I think it’s important we have nine justices.”

The White House said Trump will announce his candidate for a Supreme Court justice on Saturday.

The 87-year-old Ginsburg, one of the nine judges on the Supreme Court and a liberal supported by Democrats and Republicans, died on 18 September of complications from metastatic pancreatic cancer. Before her passing, the Supreme Court had a 5-4 conservative majority, but some justices, like John Roberts have often ruled in agreement with more liberal justices.

The move by Trump and the Republicans to fill the vacancy just six weeks before the 3 November presidential election is being contested by Democrats, who note that former US President Barack Obama did not fill a vacancy left with the passing of Justice Antonin Scalia in 2016 before the presidential election.
