Arizona’s losing gubernatorial candidate Kari Lake filed paperwork with the Federal Elections Commission on Tuesday to run for the US Senate, the New York Times reported.
Lake, who still refuses to concede defeat in the 2022 gubernatorial election, hopes to challenge incumbent Senator Kyrsten Sinema who has not yet confirmed if she will seek a second term.
Arizona Democrat Rep. Ruben Gallego has already announced that he is challenging Sinema, who changed her party affiliation from Democrat to Independent last year.
Lake was in Washington on Tuesday meeting with several Republican senators, including Wisconsin Senator Ron Johnson and Texas Senator John Cornyn. She also met with NRSC chairman Steve Daines (R-MT) who is considering whether to endorse Lake in the race.
Blake Masters, who lost his Senate bid against Mark Kelly in 2022, has also indicated that he might run for the Republican nomination in Arizona.
In August, the Wall Street Journal reported Masters planned to enter the race. However, he has not yet filed paperwork with the FEC.
Pinal County Sheriff Mark Lamb, an ally of Donald Trump, is also running for the Republican nomination.
Earlier this year, Lake revealed that she was considering a Senate run while continuing to claim she was the rightful governor of Arizona.
In 2022, Lake lost to Katie Hobbs by more than 17,000 votes and has spent the last year claiming that her loss was due to election fraud.
In December, Lake filed a lawsuit accusing election officials in Maricopa County of deliberate misconduct, but a judge rejected the claims.
In March, the Arizona Supreme Court declined to hear her appeal and sent a single complaint back to the trial court for a review. But in May, her challenge over signature verification on mail-in ballots was thrown out by a lower court judge. Lake appealed the decision in September.
