Washington — The Colorado Supreme Court ruled Tuesday that former President Donald Trump is disqualified from holding the presidency under the Constitution's so-called insurrection clause and ordered the secretary of state to exclude his name from the Republican presidential primary ballot. The landmark decision from the divided Colorado Supreme Court that Trump cannot hold public office under the Civil War-era provision is unprecedented, and it marks the first time a court has found him to be ineligible to return to the White House due to his conduct surrounding the Jan. 6, 2021, attack on the U.S. Capitol. Never before has a court determined that a presidential candidate is disqualified under clause, Section 3 of the 14th Amendment.
