Incumbent Democratic Sen. Mark Kelly defeated Republican Blake Masters on Friday to win a U.S. Senate seat in Arizona, a contest that left Democrats one seat short in the battle for control of the chamber with two more races to be decided.
The win by Kelly, a former astronaut whose wife, Gabby Giffords, survived an assassination attempt when she was a U.S. lawmaker, meant Democrats had battled to a 49-49 tie in the race for the Senate.
"I'm humbled by the trust our state has placed in me to continue this work," Kelly said on Twitter.
