Kari Lake launches Senate bid after gubernatorial defeat

Lake, who lost her bid for Arizona governor in 2022, filed paperwork to challenge incumbent Senator Kyrsten Sinema.
Lake ran an unsuccessful gubernatorial campaign promoting election conspiracy theories and hardline immigration policies echoing Trump.
She spent months contesting her gubernatorial loss in court, but judges dismissed her cases citing lack of evidence.
Lake is now seeking ballot envelope signatures for a third legal challenge of the 2022 election she lost.
If elected, Lake would bring her disputed views on the 2020 election and border security to the Senate.
