Donald Trump has asked the US Supreme Court to reverse a Colorado ruling that barred him from running for president in that state.

Colorado's top court said last month Mr Trump was not an eligible candidate as it said he had engaged in insurrection over the US Capitol riot.
His appeal comes a day after he challenged a similar decision by Maine.
Dozens of lawsuits have been filed in multiple states seeking to disqualify Mr Trump from the November 2024 ballot.
Courts in Minnesota and Michigan have dismissed similar efforts to disqualify the former US president.
In other states, such as Oregon, cases revolving around the current Republican frontrunner's eligibility are still pending.
A US Supreme Court ruling on the issue of Mr Trump's eligibility would be binding nationwide.
In Maine and Colorado, Mr Trump was removed from the ballot after legal challenges that accused him of inciting the US Capitol riot of 6 January 2021.
The 14th Amendment of the US Constitution bans anyone who has "engaged in insurrection or rebellion" from holding federal office.
In a statement, the Trump campaign accused the Colorado Supreme Court and President Joe Biden, a Democrat, of "doing all they can to disenfranchise all American voters by attempting to remove President Trump".
"This is an un-American, unconstitutional act of election interference which cannot stand," campaign spokesman Steven Cheung added.
"We urge a clear, summary rejection of the Colorado Supreme Court's wrongful ruling and the execution of a free and fair election in November."
The Colorado Supreme Court decision was narrow, with four judges in favour and three against. All seven justices were appointed by Democratic governors.
