CAMDEN, Maine — Maine's top election official ruled Thursday that Donald Trump is constitutionally ineligible to appear on the state's primary ballot next year, fueling a national effort to disqualify the former president over his attempts to overturn the 2020 election.

The decision by Maine Secretary of State Shenna Bellows, a Democrat, follows a bombshell Colorado Supreme Court ruling last week that concluded the 14th Amendment to the Constitution prohibits Trump from serving in office again due to his role in the Jan. 6 attack on the Capitol.
