Today, Treasury Secretary Jack Lew gave an interview to Scott Pelley. In the clip below, he attempts to bat aside the IRS targeting scandal by asserting that there’s “no evidence” any political employee was involved in the targeting.

It sounds good, of course — but his “no evidence” formulation, designed to suggest the administration’s innocence (i.e., that “no evidence” exists), means only that investigators have so far been prevented from uncovering all the facts. When a key witness takes the Fifth; the President’s hand-picked new IRS chief misleadingly “reports” that lefty groups were targeted, too; and Democrats seek to attack the Inspector General rather than get to the truth, then it’s entirely foreseeable that evidence will take a while to emerge, but that doesn’t necessarily mean it doesn’t exist.
