In a recent campaign email, Utah Republican Governor Spencer Cox faced criticism for including a photo of him and Donald Trump at Arlington National Cemetery during a wreath-laying ceremony.

Federal law prohibits campaign or election-related activities within Army National Military Cemeteries, and that rule was widely shared before the ceremony at Arlington National Cemetery on Monday.

Cox’s campaign apologized for using the photo and politicizing the graveside ceremony, which honored Sgt. Darin Taylor Hoover of Utah, one of 13 individuals who died in Afghanistan three years ago. The email was soliciting donations for his reelection bid.

“This was not a campaign event and was never intended to be used by the campaign,” the governor wrote in a post. “It did not go through the proper channels and should not have been sent.”

Trump’s campaign also faced backlash after an altercation with cemetery workers. The campaign was warned about not taking photographs before the incident at Arlington National Cemetery, where a wreath-laying ceremony was being held to honor service members killed in the Afghanistan War withdrawal.

Despite the controversy, Cox is expected to win reelection comfortably in November, following his victory in the primary over an ardent Trump supporter. His recent pledge of support to Trump has raised eyebrows, as it represents a significant departure from his previous statements regarding the former president.

Democratic state Rep. Brian King criticized the use of the veterans’ memorial event as a campaign photo-op and called on Governor Cox to rescind his Trump endorsement.
