Mike Pence endorses GOP rival of Trump-backed candidate for Arizona governor

Former Vice President Mike Pence on Monday endorsed Karrin Taylor Robson, who is running against Trump-backed, former TV news anchor Kari Lake in the GOP primary for Arizona governor.

The endorsement further escalated the public rift between Mr. Pence and his former boss, teeing up another high-profile intraparty showdown ahead of the Aug. 2 primary.

Ms. Robson, a real estate developer and former member of the Arizona Board of Regents, is “the best choice for Arizona’s future” who will “keep Arizona’s border secure and streets safe, empower parents and create great schools, and promote conservative values,” Mr. Pence said.

“I am honored to announce the endorsement of former Vice President @Mike_Pence,” Ms. Robson tweeted. “He has been a warrior for the sanctity of Life; limited government; law & order; opportunity for all; & the knowledge that our freedoms are granted by God. I’m proud to have him on my team.”
