In an interview broadcast Sunday night on C-SPAN, Coburn said the notion that he is retiring due to the cancer is false, saying he made the decision to leave the Senate “about four months” before he learned that it had returned.
“My patience is running thin with the way Congress works,” he said. “I’m bowing out of the Senate, but I’m not bowing out of the debate,” Coburn added.
Coburn, who announced in January that he’d retire at the end of the year, is forgoing the final two years of his term. He's also suffered from melanoma and colon cancer.
