Former US president Donald Trump on Wednesday asked the US Supreme Court to review a ruling barring him from the Colorado ballot, setting up a high-stakes showdown over whether a constitutional provision prohibiting those who “engaged in insurrection” will end his political career.

Mr Trump appealed against a 4-3 ruling in December by the Colorado Supreme Court that marked the first time in history that Section 3 of the 14th Amendment was used to bar a presidential contender from the ballot.
