Gov. Ron DeSantis will announce a run for president on Wednesday in a Twitter Spaces session with the company’s outgoing CEO Elon Musk, two people familiar with the matter confirmed to POLITICO.

Florida’s 44-year-old governor’s entry into the race will immediately shake up a Republican primary that has been dominated by former President Donald Trump.

The news of DeSantis’ plans was first reported by NBC. Twitter Spaces is the social media site’s audio gathering platform.
