Doug Burgum has become the latest Republican presidential candidate to suspend his campaign.
On Monday, Mr Burgum, the governor of North Dakota, announced he was dropping out of the race, just ahead of the fourth GOP debate which Mr Burgum did not qualify for.
In his statement, Mr Burgum criticised the Republican National Committee (RNC) for placing “arbitrary criteria” on candidates.
“None of their debate criteria relate to the qualifications related to actually doing the job of the president. This effort to nationalize the primary system is unhealthy for the future of the party,” Mr Burgum said.
The North Dakota governor joins former Vice President Mike Pence and South Carolina Senator Tim Scott in recusing themselves from the race.
The remaining GOP candidates are frontrunner and former President Donald Trump, former UN Ambassador and South Carolina Governor Nikki Haley, Florida Governor Ron DeSantis, biotech entrepreneur and anti-woke author Vivek Ramaswamy, former New Jersey Governor Chris Christie, and former Arkansas Governor Asa Hutchinson.
