The justices hear arguments next month on whether Trump can be barred from office for his efforts to overturn the 2020 election results that culminated in the Jan. 6 Capitol attack.

Colorado voters who say former President Donald Trump should be barred from holding federal office because of his role in the events leading up to the Jan. 6 attack on the Capitol urged the Supreme Court on Friday to kick him off their state’s Republican primary ballot.

Trump “intentionally organized and incited a violent mob to attack the United States Capitol in a desperate attempt to prevent the counting of electoral votes cast against him,” lawyers for the voters said in a new brief.

“By spearheading this attack, Trump engaged in insurrection against the Constitution,” the lawyers wrote.

The case addresses whether Section 3 of the 14th Amendment, which bars those who have “engaged in insurrection” from holding federal office, applies to Trump.

The court is hearing oral arguments on Feb. 8.
