The Colorado Supreme Court ruled on Tuesday that former President Donald J. Trump is barred from holding office under the 14th Amendment, which disqualifies those who engage in insurrection, and directed Mr. Trump\u2019s name to be excluded from the state\u2019s 2024 Republican primary ballot. Adam Liptak, who covers the court for The New York Times, explains the ruling and why the case is likely headed to the U.S. Supreme Court.
