The Hobbs Act defines extortion, in relevant part, as "the obtaining of property from another, with his consent, ... under color of official right." 18 U.S.C. $ 1951(b)(2). This Court has held that a public official violates that statute when he "obtain[s] a payment to which he was not entitled, knowing that the payment was made in return for official acts." Evans v. United States, 504 U.S. 255, 268 (1992). The question presented, on which the Fourth and Sixth Circuits explicitly disagree, is: Does a conspiracy to commit extortion require that the conspirators agree to obtain property from someone outside the conspiracy?
