The US Supreme Court has ruled that Colorado cannot disqualify Donald Trump from its Republican presidential primary. Colorado barred Mr Trump from the state's ballot in December, citing an insurrection clause of the Constitution and arguing the former president incited the 2021 Capitol riot. Mr Trump immediately claimed victory following the ruling, taking to his Truth Social media platform to claim a "big win for America". Two other states, Maine and Illinois , followed Colorado in kicking Mr Trump off the ballot on similar ground. The efforts in both states were put on hold while his challenge to the Colorado ruling was escalated to the Supreme Court.
