19. The best route for the House Democrats is to continue investigations.

Not sure a mandamus action would work for Congress. The specifies a party to whom the duty is owed. Congress is generally not a part of that group. It would be. A duty owed the “people”, not another branch of government.

Much like how other suits have been dismissed for lack of an injured party. Haven’t read the opinion but am assuming lack of standing was at least part of the appellate court’s rationale dismissing the Congreesional suit for violations of the emoluments clause.

For emoluments it would probably be best brought by businesses impacted by loss of business income due to the President’s ownership of a competitor.

Not sure who would have standing in the case of Barr. It does, however fall directly within the powers of congressional oversight.
