(AP) — A northeast Kansas prosecutor says he’s considering a run for the U.S. Senate next year as a Democrat.

Shawnee County District Attorney Chad Taylor confirmed Friday to The Associated Press that he plans to form a committee to explore a bid for the seat held by veteran Republican Pat Roberts.

Taylor said he’ll make a formal announcement on his 40th birthday Monday. He declined to discuss details until then.

Taylor is the first Democrat to publicly announce an interest in the race. He’s been district attorney of the county that includes Topeka since 2009.

Roberts has held the Senate seat since 1997. He faces Republican primary opposition from Leawood radiologist Milton Wolf.
