The general perjury statute, 18 U.S.C. § 1621, also applies to grand jury testimony and has similar elements, except that it requires that the witness have acted willfully and that the government satisfy “strict common-law requirements for establishing falsity.” See Dunn v. United States, 442 U.S. 100, 106 & n.6 (1979) (explaining “the two-witness rule” and the corroboration that it demands). Obstruction of Justice. Three basic elements are common to the obstruction statutes pertinent to this Office’s charging decisions: an obstructive act; some form of nexus between the obstructive act and an official proceeding; and criminal (i.e., corrupt) intent. A detailed discussion of those elements, and the law governing obstruction of justice more generally, is included in Volume II of the report. b. Application to Certain Individuals i.

This account was false. Papadopoulos met Mifsud for the first time on approximately March 14, 2016, after Papadopoulos had already learned he would be a foreign policy advisor for the Campaign. Mifsud showed interest in Papadopoulos only after learning of his role on the Campaign. And Mifsud
