The court should satisfy itself, by inquiry of the defendant or the attorney for the government, or by examining the presentence report, or otherwise, that the conduct which the defendant admits constitutes the offense charged in the indictment or information or an offense included therein to which the defendant has pleaded guilty. Such inquiry should, e.g., protect a defendant who is in the position of pleading voluntarily with an understanding of the nature of the charge but without realizing that his conduct does not actually fall within the charge. For a similar requirement see Mich. Stat. Ann. §28.1058 (1954); Mich. Sup. Ct. Rule 35A; In re Valle, 364 Mich. 471, 110 N.W.2d 673 (1961); People v. Barrows, 358 Mich. 267, 99 N.W.2d 347 (1959); People v. Bumpus, 355 Mich. 374, 94 N.W.2d 854 (1959); People v. Coates, 337 Mich. 56, 59 N.W.2d 83 (1953). See also Stinson v. United States, 316 F.2d 554 (5th Cir. 1963).
