Kyrsten Sinema, the first and still only out bisexual U.S. senator, has endorsed Joe Biden for president.
Sinema, a Democrat from Arizona, tweeted her support for Biden Wednesday afternoon, a day after the former vice president racked up several Democratic primary victories on Super Tuesday.
Biden's other endorsers in Arizona, according to his campaign, include Mark Kelly, the former astronaut running for Arizona's other U.S. Senate seat; Congressman Greg Stanton; former U.S. Sen. Dennis DeConcini; Arizona Corporation Commission member Sandra Kennedy; and former Phoenix Mayor Phil Gordon. The state will hold its presidential primary March 17.
