The US Supreme Court has said it will hear a historic case to determine if Donald Trump can run for president.
The justices agreed to take up Mr Trump’s appeal against a decision by Colorado to remove him from the 2024 ballot in that state.
The case will be heard in February and the ruling will apply nationwide.
Lawsuits in a number of states are seeking to disqualify Mr Trump, arguing that he engaged in insurrection during the US Capitol riot three years ago.
The legal challenges hinge on whether a Civil War-era constitutional amendment renders Mr Trump ineligible to stand as a candidate.
The Supreme Court’s decision to hear Mr Trump’s appeal came after attorney generals from 27 states filed a brief asking the court to reject Colorado’s ruling.
In it, they argue that removing Mr Trump from the ballot would “create widespread chaos”.
The 14th Amendment of the US Constitution bans anyone who has “engaged in insurrection or rebellion” from holding federal office, but the former president’s lawyers argue it does not apply to the president.
This is the first time the Supreme Court will consider how to interpret the clause.
Mr Trump is the current Republican front-runner for a likely rematch against President Joe Biden, a Democrat, in this November’s election.
Courts in Minnesota and Michigan have dismissed attempts to disqualify Mr Trump. Other cases, including in Oregon, are pending.
The US Supreme Court has a conservative majority – with three justices appointed by Mr Trump when he was president.
But they overwhelmingly ruled against him in his lawsuits challenging his defeat to Mr Biden in 2020.
The court on Friday agreed to take up the case in an expedited manner, with oral arguments scheduled for 8 February.
Mr Trump’s legal team is due to file their opening brief by 18 January.
The group arguing for Mr Trump’s disqualification must submit its argument by 31 January.
