The Court held in Kisor v. Wilkie, 139 S. Ct. 2400 (2019),
that before a court may defer to an agency's interpretation of its
regulation, the court must find that the regulation is genuinely
ambiguous. In Stinson v. United States, 508 U.S. 36 (1993), the
Court held that district courts must heed the Sentencing
Commission's commentary to a sentencing guideline because the
commentary provides "concrete guidance as to how even
unambiguous guidelines are to be applied in practice." Did Kisor
abrogate Stinson's holding, as four circuits have held, or does the
holding survive because the Commission is not an executive
agency and the guidelines it issues are advisory, as at least two
circuits have held?

Did Kisor abrogate Stinson's holding?
