The Colorado Supreme Court has disqualified Donald Trump from Colorado's 2024 presidential election ballot, and in a 4-3 ruling has effectively blocked Trump from seeking the presidency because of his role in the Jan. 6 Capitol attack, citing the post-Civil War-era 14th Amendment to the US Constitution that bans insurrectionists from holding public office. The Colorado case was the first constitutional challenge to Trump's 2024 run to go through a full trial.

Voters, represented by the advocacy group Citizens for Responsibility and Ethics, had argued he should be barred from the ballot for inciting the Jan. 6, 2021 attack on the US Capitol.

Colorado's highest court - whose seven-member bench was entirely appointed by Democratic governors - overturned a ruling from a district court judge who found that Trump incited an insurrection for his role in the Jan. 6, 2021, attack on the Capitol, but said he could not be barred from the ballot because it was unclear that the provision was intended to cover the presidency.
