1081 86-87, 120-129, 162. 4. General Principles of Statutory Construction Do Not Suggest That Section 1512(c)(2) is Inapplicable to the Conduct in this Investigation The requirement of fair warning in criminal law, the interest in avoiding due process concerns in potentially vague statutes, and the rule of lenity do not 1082 justify narrowing the reach of Section 1512(c)(2)’s text. a. As with other criminal laws, the Supreme Court has “exercised restraint” in interpreting obstruction-of-justice provisions, both out of respect for Congress’s role in defining crimes and in the interest of providing individuals with “fair warning” of what a criminal statute prohibits. Marinello v. United States, 138 S. Ct. 1101, 1106 (2018); Arthur Andersen, 544 U.S. at 703; Aguilar, 515 U.S. at 599-602. In several obstruction cases, the Court has imposed a nexus test that requires that the wrongful conduct targeted by the provision be sufficiently connected to an official proceeding to ensure the requisite culpability. Marinello, 138 S. Ct. at 1109; Arthur Andersen, 544 U.S. at 707-708; Aguilar, 515 U.S. at 600-602. Section 1512(c)(2) has been interpreted to require a similar nexus. See, e.g., United States v. Young, 916 F.3d 368, 386 (4th Cir. 2019); United States v. Petruk, 781 F.3d 438, 445 (8th Cir. 2015); United States v. Phillips, 583 F.3d 1261, 1264 (10th Cir. 2009); United States v. Reich, 479 F.3d 179, 186 (2d Cir. 2007). To satisfy the nexus requirement, the government must show as an objective matter that a defendant acted “in a manner that is likely to obstruct justice,” such that the statute “excludes defendants who have an evil purpose but use means that would only unnaturally and improbably be successful.” Aguilar, 515 U.S. at 601-602 (internal quotation marks omitted); see id. at 599 (“the endeavor must have the natural and probable effect of interfering with the due administration of justice”) (internal quotation marks omitted). The government must also show as a subjective matter that the actor “contemplated a particular, foreseeable proceeding.” Petruk, 781 F.3d at 445. Those requirements alleviate fair-warning concerns by ensuring that obstructive conduct has a close enough connection to existing or future proceedings to implicate the dangers targeted by the obstruction laws and that the individual actually has the obstructive result in mind. b. Courts also seek to construe statutes to avoid due process vagueness
