The US Supreme Court has struck down efforts by individual States to bar Donald Trump from running as a presidential candidate for November’s election.

Justices unanimously overruled Colorado’s decision to disqualify Trump from the Republican primary ballot.

Judges in the state had cited an anti-insurrection clause in the US Constitution to ban Trump; similar attempts have been made in Illinois and Maine.

The Colorado ruling pointed to Trump’s actions around the January 6 attack on the Capitol by his supporters.

But in their decision announced on Monday morning, justices ruled that only Congress has the power to enforce the provision, not states.
