David Perdue, the Trump-backed former senator, plans to announce he’ll challenge Georgia Gov. Brian Kemp in a Republican primary face-off next year, a source familiar with Perdue’s plans has confirmed to Fox News.

Perdue, who was narrowly defeated by now-Democratic Sen. Jon Ossoff in last January’s Senate runoffs, was recruited by former President Donald Trump to oust Kemp over his refusal to help the then-president’s efforts last year to overturn the election results in Georgia.

Sources told Politico that Perdue expects to receive further fundraising and endorsement support from Trump ahead of the Georgia Republican primary. He intends to make his announcement Monday via video and file his paperwork at the same time, the report said.
