WASHINGTON (AP) — The Supreme Court has scheduled a special session to hear arguments over whether former President Donald Trump can be prosecuted over his efforts to undo his 2020 election loss to President Joe Biden.

The case, to be argued Thursday, stems from Trump’s attempts to have charges against him dismissed. Lower courts have found he cannot claim for actions that, prosecutors say, illegally sought to interfere with the election results.

The Republican ex-president has been charged in federal court in Washington with conspiring to overturn the 2020 election, one of four criminal cases he is facing. A trial has begun in New York over hush money payments to a porn star to cover up an alleged sexual encounter.

The Supreme Court is moving faster than usual in taking up the case, though not as quickly as special counsel Jack Smith wanted, raising questions about whether there will be time to hold a trial before the November election, if the justices agree with lower courts that Trump can be prosecuted.
