Another Arizona lawmaker wants to take over for Senator Jeff Flake. Representative Martha McSally has reportedly told Republican colleagues that she's running for the U.S. Senate seat.
McSally hasn't made a formal announcement but she would be going head to head with former state Senator Kelli Ward.
Democratic Representative Kyrsten Sinema is seeking her party's nomination for the seat.
McSally's voting record has made her the most supportive of President Trump's agenda among Arizona's House members.
