When defendant s plead guilty, this Court's precedent —consistent with due process —require s that they understand the offense's essential elements. In Rehaif v. United States , 139 S. Ct. 2191 (2019) , this Court recognized that knowledge of one's status as a person prohibited from possessing a firearm is an essential element under 18 U.S.C. § 922(g) . Can a court, as the Third Circuit did here, treat a plea as constitutionally valid when it was entered without knowledge of an offense element ?

When defendants plead guilty, can a court treat a plea as constitutionally valid when it was entered without knowledge of an offense element?
