“They’re inherent in its roles and responsibilities.”
Only through judicial extension.
And that’s certainly what any progressive would have everyone believe.

No mention in the Constitution that Congress has a responsibility to ensure and/or enforce anything. Nor any right to access anything in government. Or anything from the Executive.
The entire concept is in flux all the time because it is extra-constitutional and both Congress and the Executive have de facto agreement to allow the courts to arbitrate.
But the Constitution does not grant the courts this power. Nor is oversight granted to Congress.
Does Congress have oversight authority if an executive declines to comply with their demands, or the demands of the court?
No, also through common sense and the historical roles of public legislatures.
As Heritage says:
”Congressional oversight, derived from the implied powers in the U.S. Constitution and conducted since the earliest days of our Republic, is an essential tool in maintaining the separation of powers. In the decades since the New Deal, oversight has taken on additional importance as a needed restraint on the ever-expanding administrative state. During the Constitutional Convention, George Mason referred to this authority when he said that Members of Congress “are not only Legislators but they possess inquisitorial powers. They must meet frequently to inspect the Conduct of the public offices.” This important investigatory role includes the review, monitoring, and close scrutiny of federal agencies, programs, activities, and policy implementation, as well as anywhere that federal tax dollars flow, to ensure faithful compliance with congressional intent.”
A position that’s long been upheld by SCOTUS and recognized by all three branches.
Does Congress have oversight authority if an executive declines to comply with their demands, or the demands of the court?
I think we might be about to find out.
If SCOTUS says the accounting firm has to provide the documents they will, or face criminal penalties.
