The opinion also unsurprisingly holds, though technically as a matter of first impression in this Circuit, that the particular version of the obstruction law embodied in 18 U.S.C. § 1512(c)(2) -- punishing anyone who "corruptly ... obstructs, influences, or impedes any official proceeding, or attempts to do so" -- includes a "nexus" requirement. That is, the defendant's allegedly obstructive act must "have a relationship in time, causation, or logic with the judicial proceedings; in other words, the endeavor must have the natural and probable effect of interfering with the due administration of justice." Op. 10-11 (quoting United States v. Aguilar, 515 U.S. 593, 599 (1995)).
