Updated: The Associated Press declared Dan Sullivan the winner of the U.S. Senate race in Alaska late Tuesday night, saying "it became evident Tuesday when the state began counting about 20,000 absentee and questioned ballots that Begich could not overcome his opponent." 

Incumbent Mark Begich had not conceded Wednesday morning. "Sen. Begich believes every vote deserves to be counted in this election," campaign manager Susanne Fleek-Green said in an email to The Associated Press. "There are tens of thousands of outstanding votes and Sen. Begich has heard from rural Alaskans that their votes deserve to be counted and their voices deserve to be heard. He will honor those requests."
