WASHINGTON: Retired football star Herschel Walker, an ally of former President Donald Trump, filed paperwork on Tuesday to run for the US Senate in Georgia, as Republicans try to win back one of the two seats they lost in January runoff elections.
Walker filed the documentation with the US Federal Election Commission to seek the Republican nomination to challenge Democratic Senator Raphael Warnock in the November 2022 election.
The Atlanta Journal-Constitution reported that a formal announcement of his candidacy was expected within days.
Walker, 59, was a football star at the University of Georgia, winning the 1982 Heisman Trophy as the nation's most outstanding collegiate player, before playing professional football for the New Jersey Generals of the now-defunct USFL - a team that was owned by Trump - and later in the National Football League.
He did not immediately respond to a request for comment.
Warnock, a pastor from Atlanta, and fellow Democrat Jon Ossoff won runoff elections in Georgia, giving President Joe Biden's party control over the Senate.
Democrats hold narrow majorities in the Senate and the House of Representatives, and losing control of either next year would be a blow to Biden.
Trump had publicly urged Walker to run. Walker, who is black, had waded more deeply into conservative politics over the past year, notably with a speech defending Trump from accusations of racism.
"I take it as a personal insult that people would think I would have a 37-year friendship with a racist," Walker told the Republican National Convention in August 2020.
In March of this year, Walker appeared by video link at an event in which Kristi Noem, the Republican governor of South Dakota, advocated for barring transgender girls and women from participating in female sports.
