The decision came two weeks after the court said Colorado could not use that same provision to remove Trump from the presidential ballot because he's a federal candidate.
Couy Griffin, a founder of Cowboys for Trump, is the only person who participated in the Jan. 6, 2021, attack on the U.S. Capitol to be removed from office using the 14th Amendment.
The challenge to Griffin had been a test run for Trump opponents who successfully argued to the Colorado Supreme Court last year that Trump is disqualified from the presidency by that same Civil War-era provision.
