(CNN) - Michele Bachmann became the latest candidate to decline Donald Trump's invitation to his upcoming Republican presidential debate, her top spokesperson, Alice Stewart, told CNN.
She's the fifth candidate to turn down the offer, leaving former Pennsylvania Sen. Rick Santorum and former House Speaker Newt Gingrich as the only two candidates scheduled to face off at the event.
Trump and Newsmax, a conservative magazine, will host the debate on Dec. 27.
Bachmann has met with Trump multiple times on the campaign trail. With his highly-prized endorsement, his offices in New York City have become a popular stop for several of the GOP presidential candidates.
