At last, at least for your humble correspondent, this week’s big hearing brought clarity. I now believe President Donald Trump fired Federal Bureau of Investigation director James Comey because he believes Comey intentionally misled the public into believing Trump was under investigation by the FBI. There is enough support for this theory that, had the president been forthright in explaining it when he dismissed Comey on May 9, there might have been considerably less uproar. Instead, Trump dissembled, as he seems hardwired to do. He thus bought himself a debilitating special-counsel investigation, despite its being increasingly patent that there is no crime to investigate.
