her Democratic opponent, Representative Ruben Gallego, announced a coalition of dozens of Republican and independent Arizona leaders supporting him.

Lake, a fierce supporter of former President Donald Trump and a 2020 election denier who backs "America First" policies, will go up against Gallego, a fifth-term U.S. congressman and former U.S. Marine who served in Iraq, in November for the seat of Senator Kyrsten Sinema, a Democrat turned independent who is not seeking reelection. Lake ran for Arizona governor in 2022 against Democrat Katie Hobbs. However, when Lake lost, she claimed the election was stolen, just like the claims she has made about Joe Biden's 2020 election victory. There is no evidence to support widespread voter fraud in the 2020 presidential election or Arizona's 2022 gubernatorial election.

On Sunday, Gallego's campaign launched "Republicans and Independents for Ruben," a coalition of 40 Arizona Republicans and independents—which include current and former elected officials as well as industry experts, business owners and community leaders—who have endorsed the congressman.

"I am running for the U.S. Senate to represent all Arizonans, regardless of where they live or what political party they align themselves with. We may not agree on everything, but we can find common ground on one essential goal: building a better Arizona. And as a Marine combat veteran, a Congressman, and a dad of two, that is one fight I will never give up on," Gallego said in the press release announcing the coalition on Sunday.
