"We cannot afford a divisive Republican primary that drains resources and turns into months of intraparty attacks. It only weakens our conservative cause and gives the left exactly what they want: a fractured Republican Party heading into November. With so much on the line in 2026, I am not willing to contribute to that outcome," she noted in the statement.
Robson did not make an endorsement.
"I remain committed to helping Republicans win in 2026 and to ensuring Arizona remains strong, safe, and free for generations to come," she noted in the statement.
Trump had pledged to support her for governor in 2024.
"Are you running for governor? I think so, Karrin, cuz if you do, you're gonna have my support," Trump said at Turning Point USA's AmericaFest in December 2024.
