Herschel Walker files to run for US Senate in Georgia

Former University of Georgia football legend Herschel Walker has filed to run for U.S. Senate in Georgia, becoming the most prominent Republican to line up to challenge incumbent Sen. Raphael Warnock (D-Ga.).

Walker, a Texas resident, was long rumored as a potential candidate and was heavily lobbied by former President Donald Trump to move to Georgia and run for Senate. Earlier this month, Walker registered to vote there, leading many to suspect that an official announcement of his candidacy was imminent.

The Atlanta Journal-Constitution first reported that Walker filed with the Federal Election Commission Tuesday. A public statement announcing his candidacy is expected within days.

Trump was an early supporter of Walker for Senate, saying in March he would be "unstoppable" as a candidate.
