perpetration, which produces an ongoing threat of harm. See Brazell, 489 F.3d at 668; Yashar, 166 F.3d at 875. The prototypical continuing offense is conspiracy, which “continues as long as the conspirators engage in overt acts in furtherance of their plot,” and “each day’s acts bring a renewed threat of the substantive evil Congress sought to prevent.” Toussie, 397 U.S. at 122, 90 S.Ct. 858. Likewise, other offenses that prohibit an individual from remaining in an unlawful condition or status have been construed to continue so long as the offender maintains the unlawful condition or status; the perpetration of the offense naturally continues so long as the unlawful condition is maintained. See, e.g., United States v. Bailey, 444 U.S. 394, 413, 100 S.Ct. 624, 62 L.Ed.2d 575 (1980) (<HOLDING>); Cores, 356 U.S. at 408-09, 78 S.Ct. 875
