Presidential candidate Donald Trump is to appear before a federal court in Washington, D.C. He is accused of trying to overturn the results of last year's election.

He lost to Democrat Joe Biden, who is now running for re-election. The case is expected to be heard by the end of the month, but no date has been set for when it will be heard, a spokesman said. The court will decide if the case should go to the Supreme Court or a lower court, he said.
