Today the US Supreme Court will hear the case of Donald J Trump v Norma Anderson et al. The case being considered is whether the 14th amendment to the constitution prohibits Trump from holding office because of his conduct on 6 January 2021. Section 3 of the amendment says that any member of Congress or officer of the United States who takes an oath to protect the constitution and then subsequently engages in insurrection cannot hold office. That ban, the amendment says, can only be overridden by a two-thirds vote of each house of Congress. There is no precedent for the case. The 14th amendment, enacted after the civil war, has never been used to challenge the eligibility of a presidential candidate. After a 5 day trial, a Colorado district court judge said Trump had committed insurrection, but was not disqualified because he was not an officer of the United States. The Colorado supreme court reversed that ruling in December, removing Trump from the ballot in a 4-3 decision. Oral argument is set for 80 minutes.
