Cartwright released a statement Thursday night apologizing for what he called an “insensitive” remark.

“I want to express my deep admiration for Senator McCain and gratitude for his service to our nation,” he said. “I have reached out to apologize directly to him and his family for my statement about his illness, which I agree was insensitive, and which has clearly offended the McCain family. I know he will continue to fight for the people of Arizona and this country during his courageous battle with this disease. I wish a full and speedy recovery.”
