WASHINGTON (Reuters) -Retired football star Herschel Walker, an ally of former President Donald Trump, filed paperwork on Tuesday to run for the U.S. 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 U.S. Federal Election Commission to seek the Republican nomination to challenge Democratic Senator Raphael Warnock in the November 2022 election.
