Just skimmed the bill...not sure that it does anything that agencies couldn't do now. But, maybe he has taken issue with this part:
c) MEMBERS.—The interagency working group shall be composed of such representatives of Federal departments and agencies as the Attorney General considers appropriate, such as— (1) the Department of Commerce; (2) the Department of State; (3) the Department of Homeland Security; (4) the Federal Communications Commission; (5) the Federal Trade Commission; and (6) the Consumer Financial Protection Bureau. (d) NON-FEDERAL STAKEHOLDERS.—In carrying out the study under subsection (a), the interagency working group shall consult with such non-Federal stakeholders as the Attorney General determines have the relevant expertise, including the National Association of Attorneys General.
No risk of overreach beyond the bill's intent there
