Third 'long-shot' in bid for Republican primary
Former congressman Mark Sanford has become the latest long-shot contender to challenge Donald Trump in the Republican Party primary.
"I'm here to tell you now that I am going to get in," Mr Sanford said yesterday, adding that he will formally launch his bid for the party's 2020 White House nomination in South Carolina later this week.
He becomes the third Republican to enter the race to challenge Mr Trump.
Former Massachusetts governor Bill Weld and former US representative from Illinois Joe Walsh have also launched long-shot campaigns, but neither of these candidates has gained traction.
Mr Sanford (59), a long-time Trump critic, lost his seat for South Carolina in the House of Representatives last year after he was beaten by a Trump supporter in the Republican primary.
He said he wanted to run to give Republicans an alternative to Mr Trump with "executive experience" and restore the party to its principles.
