More memos, more confusion

The Republicans released Rep. Nunes' memo first.

Democratic representative Jerrold Nadler came out with a memo Sunday - not subject to committee review.
Andrew McCarthy wasn't impressed.

He posits four points, the last two of which are strictly political red meat. Of the other two, one provides an inaccurate explanation of the probable-cause standard in the Foreign Intelligence Surveillance Act (FISA); the other is an ill-conceived argument about Christopher Steele’s credibility. The latter provides a welcome opportunity to confront a wayward theory — which I’ll call “vicarious credibility” — that has been vigorously argued by apologists for the FBI and Justice Department’s handling of the Steele dossier.
