WILMINGTON, DE — Dr. Mike Katz today announced the endorsement of former Delaware Republican Party Chair and former U.S. Attorney for Delaware Julianne Murray, a well-known figure in Delaware conservative politics whose backing further consolidates Republican support behind Katz's 2026 U.S. Senate campaign.
Announcing her endorsement, Murray emphasized that voters should focus on effectiveness against incumbent Senator Chris Coons, not partisan history.
"This race is not about party labels. It's about who is best prepared to take on Chris Coons and finally give Delaware a voice that puts our state first."
— Julianne Murray, Former U.S. Attorney & Delaware GOP Chair
Murray addressed head-on the question of Dr. Katz's political history — he previously served in the Delaware State Senate as a Democrat before becoming a Republican — arguing his trajectory reflects thoughtful conviction rather than opportunism.
"Dr. Katz was once a Democrat. Some will try to use that against him. I see it differently."
— Julianne Murray
Dr. Katz expressed his gratitude for Murray's support and reiterated the campaign's focus on the issues Delaware families care about most.
"I am honored by Julianne's support. Her career of public service and her deep understanding of Delaware make her endorsement especially meaningful. My focus in this campaign is lowering costs, border security, public safety, constitutional freedoms, and Delaware families."
— Dr. Mike Katz
Murray's endorsement joins a rapidly growing coalition of Republican leaders and grassroots organizations backing Dr. Katz's candidacy, including the Delaware Republican Party, the Independent Party of Delaware, the Northern New Castle County Republican Party, the national College Republicans of America, the Delaware College Republicans, former two-time Republican congressional nominee Lee Murphy, State Senator Dave Lawson, and other state and county Republican officials.
Dr. Katz faces the Republican primary election on September 15, 2026 against former U.S. Army Colonel John Shulli. The winner advances to the November general election against incumbent Senator Chris Coons.
The Murray endorsement was reported by Delaware LIVE.
