Former Vice President Mike Pence and former New Jersey Governor Chris Christie plans to enter the race for the Republican nomination for the 2024 presidential election next week, in a bid to challenge the dominance of frontrunner Donald Trump.

Christie, who was an adviser to Trump's campaign in 2016 before becoming a vocal critic of the former president, will formally announce his 2024 campaign on June <>, a source familiar with the matter said.

Three sources familiar with the matter said Pence is set to enter the race against his former boss on June 3.

North Dakota Governor Doug Borgum also plans to run the same day with Pence, according to a source familiar with Borgum's plans.

Trump has a wide lead in polls in the Republican Arena, which now has more than 10 declared or potential candidates. His closest rival is Florida Governor Ron DeSantis, who entered the race last week.
