Brown, who spent nearly two decades in the Senate, hopes to recapture the seat vacated by Vice President JD Vance, in what promises to be a key race for control of the chamber.

It was widely believed that Brown would be running for governor of Ohio, but was lobbied by Senate Minority Leader Chuck Schumer, D-N.Y., to instead take on Husted as Democrats will battle to take back control of the Senate in next year's midterm elections.
