President Donald Trump asked the US Supreme Court on Friday to revive his dismissed lawsuit against his 2016 Democratic rival Hillary Clinton, accusing her of conspiring along with former FBI Director James Comey and others to rig that year's election by linking his campaign to Russia.

The Republican president filed his appeal after a federal judge threw out the case and imposed nearly $1 million in sanctions against Trump and one of his lawyers for bringing a "frivolous" suit.
