Back in March 2017, he insisted that he’d seen “more than circumstantial evidence” that Trump had colluded with Russia to win the 2016 election — a claim exposed as false by the Mueller report.
He insisted that Nunes was wrong to say that the FBI’s Russia investigation relied heavily on the absurd Steele Dossier to get warrants to surveil Carter Page. Lie (unless you laughably believe he didn't know about the Dossier's importance to the warrants).
He also concealed his office's contacts with the (cough) "Ukraine Whisteblower." He vehemently insisted that “we have not spoken directly with the whistleblower,” before he was forced to acknowledge that his staff had, in fact, coordinated with the so-called whistleblower before the complaint that led to the current impeachment farce.
He completely made up the content of Trump's now-famous phone call and then had the gall to pretend that he was somehow dramatizing or joking after he got called on it.
