Whether a federal court can prosecute without verifying jurisdiction and whether the Respondent can usurp Puerto Rico's jurisdiction in violation of 18 U.S.C. §3231 when interstate commerce is not proven

Can a federal court attempt a prosecution without verifying, as the first step before any proceeding, jurisdiction? Can the Respondent take away jurisdiction from the Commonwealth of Puerto Rico in violation of 18 U.S.C. §3231 when interstate or foreign commerce has not been proven? Is the Respondent, ignoring the Commonwealth of Puerto Rico’s status as a state since 1952, usurping Puerto Rico's jurisdiction? Can the Respondent present beforea federal.grand jury an accusation with out evidence to prove jurisdiction, as in this case? Can the Respondent take to trial an accused without grand jury returning an indictment or simulate an indictment that was not filed by a grand jury as in this case? Can the Respondent take a local criminal case in Puerto Rico where the evidence does not involve the accused in interstate or foreign commerce using the Court’s foregoing case of Puerto Rico v. Sanchez-Valle, 579 U.S. 59, 71 (2016)? i
