From the Arizona Republic:
Rep. Jeff Flake, R-Ariz., will announce Monday that he will run for the U.S. Senate being vacated by Sen. Jon Kyl, a source has told The Arizona Republic.
Flake, who was first elected to Congress in 2000, has long expressed interest in running for the Senate. He will make it official at an 8 a.m. [11 a.m. EST] news conference at the same Phoenix hotel where Kyl on Thursday announced that he will retire when his current term ends in January 2013.
Stu Rothenberg tweets: “Flake candidacy in AZ Sen race gives GOP strong contender. We have the race as Lean R”
Over on the homepage, I spoke with Sen. Kyl about his decision to step down.
