Attorney General William Barr on Monday disparaged the long-awaited findings of the Justice Department Inspector General Michael Horowitz into FBI conduct in the investigation of alleged Russian interference in the 2016 presidential campaign. Barr, in effect, accused Horowitz of whitewashing a litany of proven misfeasance and malfeasance that created the "predicate," or legal justification, for investigating candidate-and-then-president Donald Trump on suspicion of being in cahoots with the Russians.

In grammatical terms, there can be no sentence, so to speak, without a predicate. Trump was clearly the object of the sentence, and the sleuths led by then-FBI Director James Comey were the subjects in desperate search of a predicate. Horowitz candidly depicted the predicate the FBI requires for a counterintelligence investigation as having to meet a very low bar. The public criticism from his boss was unusual. For the tenacious attorney general, doing a serious investigation of how the FBI handled the Trump-Russia inquiry has become a case of no-holds-Barr-ed, one might say.
