WASHINGTON — Rep. Ruben Gallego, D-Ariz., is expected to announce Monday that he's running for Senate in Arizona in 2024, according to a source familiar with his planned rollout.
Gallego, a progressive Democrat, is running for the seat held by Sinema, who decided in December to leave the Democratic Party and become an independent.
If she does, and Gallego wins the Democratic nomination, they'd face each other in the general election.
In December, after Sinema announced she was changing her party affiliation, Gallego signaled to NBC News he was likely to launch a Senate bid.
Gallego went on to say he believes if Sinema runs, “it will almost ensure the fact that the Senate seat will stay in Democratic hands” because of the GOP’s struggles to hold its coalition together.
