Kavanaugh wrote in an article for the Minnesota Law Review from 2009 that Congress should pass a law “exempting a President—while in office—from criminal prosecution and investigation, including from questioning by criminal prosecutors or defense counsel.”
“I believe that the President should be excused from some of the burdens of ordinary citizenship while serving in office,” Kavanaugh wrote. “We should not burden a sitting President with civil suits, criminal investigations, or criminal prosecutions.” Furthermore, Kavanaugh opined that the “indictment and trial of a sitting President” would “cripple the federal government.”
