Maine has become the second state to disqualify Donald Trump from the primary ballot, citing the 14th Amendment's ban on anyone who engaged in insurrection from holding office.

The decision by Maine's secretary of state, Shenna Bellows, follows a similar conclusion made on December 19 by Colorado's Supreme Court.

Trump's team on Thursday night said they will appeal the decision, as they will in Colorado. On Thursday, the Republican Party in Colorado appealed against their Supreme Court's decision, meaning that he is back on the ballot until an expected U.S. Supreme Court ruling.

Bellows, a Democrat, concluded that Trump, the frontrunner for the Republican nomination in 2024, incited an insurrection when he spread false claims about voter fraud in the 2020 election and then urged his supporters to march on the Capitol to stop lawmakers from certifying the vote.

Bellows suspended her decision until the state Supreme Court ruled on the matter.

The decision came after a group of former Maine lawmakers said that Trump should be disqualified based on Section 3 of the 14th Amendment - a provision of the U.S. Constitution that bars people from holding office if they engaged in 'insurrection or rebellion' after previously swearing an oath to the United States.

The ruling, which can be appealed to a state court, applies only to the March primary election, but it could affect Trump's status for the November general election. 

It likely will add to pressure on the U.S. Supreme Court to resolve questions about Trump's eligibility nationwide under the constitutional provision.
