In an appearance much more riveting than any reality show, former FBI Director James Comey provided his side of the events preceding his firing and thereafter. During more than two hours of sworn testimony before the Senate committee, he detailed President Trump's machinations and dissembling, including possibly attempting to obstruct justice, which made Comey so uncomfortable he asked Attorney General Jeff Sessions to provide a buffer between him and the commander-in-chief. Through his statements today Mr. Comey has thrown down a verbal gauntlet that may eventually force Mr. Trump to throw in the towel.
