BREAKING: Kari Lake WINS Arizona GOP primary

She will face off against Democrat rival Katie Hobbs in the general gubernatorial election. Blake Masters took home a tight victory as well, to become the GOP nominee for Senate.

The Republican primary was tight, with Trump-backed Lake taking 46.1 percent of the vote over Karrin Taylor Robson, who had former Vice President Mike Pence's support. Robson also had the backing of outgoing Arizona governor Doug Ducey. Lake has been a favorite among the GOP nationally.

Hobbs took 72.8 percent of the vote in her primary, while contender Marco Lopez went home with 22.2 percent.

Masters was the front-runner in the GOP ahead of Tuesday's contest against Lamon, who is in the business of solar energy. Masters was backed, too, by tech billionaire Peter Thiel, who is also Masters' former employer.

Masters took 38.9 percent of the vote over rival Jim Lamon, who had 28.9 percent. Mark Brnovich, Arizona Attorney General, gained 18.4 percent of the state's vote for his candidacy.

On election night, Arizona Republicans along with the RNC issued a joint statement slamming Pinal County, saying that they had problems with their mail-in voting procedures and practices. They jointly called for the resignation of Pinal County Elections Director David Frisk. Mail-in votes tend to favor Democrats.

Biden won Arizona in the 2020 presidential election.
