Katherine Robertson, chief counsel to Attorney General Steve Marshall, has secured the endorsement of the Republican Attorneys General Association in her campaign to become Alabama’s next attorney general.
The endorsement, announced this week, is an unusual step for the Washington-based group, which rarely intervenes in open-seat primaries. In the past 27 years, fewer than ten candidates have been endorsed by RAGA in open-seat races. RAGA leaders said Robertson’s record in Marshall’s office distinguished her from the field.
“Katherine Robertson has consistently advanced conservative legal principles and earned the trust of attorneys general across the country,” RAGA Chairman and Kansas Attorney General Kris Kobach said. “It is unusual for RAGA to endorse at this stage, but she meets that high threshold.”
Robertson has worked closely with Marshall on high-profile legal fights, including opposition to federal vaccine mandates and challenges to the Biden administration’s interpretation of Title IX. She also played a role in the state’s development of a new execution method using nitrogen hypoxia.
“Robertson has been an exemplary attorney and member of the Alabama Attorney General’s Office and comes from a long line of talented conservative Republican leaders. This is an important endorsement for RAGA considering the important role Alabama has had in the conservative legal movement and in RAGA’s history,” reads the endorsement announcement.
Her opponents in the May 2026 Republican primary are Blount County District Attorney Pamela Casey and former Alabama Supreme Court Justice Jay Mitchell. Marshall has already thrown his support behind Robertson.
The race has been shaped in recent weeks by questions about campaign financing. Robertson’s campaign has taken in $1.1 million from First Principles Action, a Tennessee nonprofit launched last year by former RAGA executive director Peter Bisbee.
Since the group is organized under federal tax law as a social welfare nonprofit, it is not required to reveal its donors.
Mitchell has labeled the money “dark funds” and accused Robertson of relying on outside influence in a state contest. Last week, he referred to the Robertson campaign as “being propped up by outsiders who want to buy Alabama’s top law enforcement office.”
RAGA’s leadership said its decision to step into the Alabama contest reflects the state’s importance to the conservative legal movement. Marshall, who cannot run again due to term limits, served as one of RAGA’s past chairmen for a year, starting in 2022.
The Republican primary for attorney general is set for May 19, 2026.
