Late in Monday’s marathon hearing of the House Intelligence Committee, FBI Director James Comey reminded the nation that he was something of a hostile witness, reluctantly summoned to talk about Russia, Donald Trump and the 2016 campaign.

“I’d rather not be talking about this at all,” Comey said. “Now we are going to close our mouths and do our work.”

Before Comey returned to his offstage role, he dropped enough bombshells to solidify his reputation as the most significant FBI director since J. Edgar Hoover. Joined by his crusty sidekick, Adm. Michael Rogers, who heads the National Security Agency, Comey gave an artful lesson in how to stick a shiv into a sitting president without ever raising his voice or making a specific accusation.

Early in the hearing, Comey shredded Trump’s cockamamie Twitter claim that Barack Obama had wiretapped him before the election. As Comey solemnly stated, “I have no information that supports those tweets and we have looked carefully inside the FBI.”

On the offensive

Comey had arrived at the hearing with his own smoking gun that he brandished at the beginning of his opening statement — official confirmation that the FBI is investigating “any links between individuals associated with the Trump campaign and the Russian government and whether there was any coordination between the campaign and Russian efforts.”
