(emphasis mine)

The White House has issued a warning to Democrats over their planned probes into the Trump administration, going as far as claiming that such investigations — a standard oversight function of Congress — may amount to “blatant criminality.”

White House counsel Will Scharf issued the warning in a letter dated Monday to Rep. Robert Garcia, the top Democrat on the House Oversight Committee.

Garcia most likely would chair the powerful panel in the new Democratic-controlled Congress that is seated in January. Garcia warned Trump officials to “lawyer up” after his party’s stunning victories in last week’s midterm elections.

In response, Scharf wrote in Monday’s letter that “threats to executive branch officials designed to deter them from public service, or process designed merely to abuse or instill fear in the recipient may cross the line into blatant criminality.” The letter’s existence was first reported by Punchbowl News.

Garcia said in response to the letter that “it appears Donald Trump has something to hide” and stressed that Congress’s investigative powers do not need the “permission of the White House.”

“Congress has wide latitude to conduct investigations and oversight, an authority inherent in the power to legislate,” Garcia said. “The American people voted overwhelmingly for us to pass laws to root out corruption and abuse.”

Democrats are preparing a vast oversight agenda to look at how Trump and his family have become wealthier since he returned to office. The Republican president and his White House have long denied any wrongdoing.

Garcia also wants to look at the administration’s handling of the Jeffrey Epstein investigation and Immigration and Customs Enforcement operations. Other targets include Trump’s White House ballroom and other construction projects, as well as the Trump family’s role in mineral deals and Trump’s crypto dealings with special envoy Steve Witkoff.

Attorney General Todd Blanche said in a CNN interview that aired Sunday that “there could be” a crime to investigate if rhetoric from Democrats turned threatening. He appeared to strike a more conciliatory tone during an appearance in Missouri this week, saying “Congress has oversight authority. It always has, it always will. The Department of Justice, the federal government, works with Congress to address questions they have — whether it’s through subpoenas or letters — so we’re not going to stop working with Congress.”

“Nothing I’ve said this weekend, or in the past, should suggest otherwise,” he added.

I researched this before, and I thought congressional oversight was limited to legislative matters and not, for example, delving into the finances of people they want to harass.

The Supreme Court on Congressional Oversight

…Watkins v. United States: The “power of the Congress to conduct investigations is inherent in the legislative process. That power is broad. It encompasses inquiries concerning the administration of existing laws as well as proposed or possibly needed statutes.”

…Trump v. Mazars USA, LLP: “Without information, Congress would be shooting in the dark, unable to legislate ‘wisely or effectively.'”

Oversight and investigative authority rests with both houses, which in turn have delegated this authority to the committees of each chamber. Committees possess only those powers that have been delegated to them by their parent bodies. Committee investigations must:

• be within the committee’s jurisdiction as defined in House or Senate rules, and

• serve a valid legislative purpose.

If these criteria are met, a committee’s investigative purview is substantial and wide-ranging.

Major Purposes of Oversight

Oversight is an implicit constitutional power of Congress. There are a number of overlapping purposes associated with oversight, which can be divided into three basic types: programmatic, political, and institutional.

Programmatic purposes include making sure agencies and programs are working in a cost-effective and efficient manner and fulfilling their statutory mission; ensuring executive compliance with legislative intent; evaluating program performance; investigating waste, fraud, and abuse; reviewing the agency rulemaking process; and acquiring information useful in future policymaking.

Political purposes include generating favorable publicity for lawmakers, winning electoral support from constituents and outside groups, and rebutting criticisms of favorite programs or agencies. Oversight occurs in an ever-present political context in which Congress’s relationship with administrative entities can range from cooperation to conflict. Moreover, there are inherent constitutional and political tensions between Congress and the President even during periods of unified government. 

Institutional purposes include checking the power of the executive branch, investigating how a law is being administered, and informing Congress and the public. These purposes may merit special mention because they serve to protect congressional prerogatives and strengthen the American public’s ability to evaluate executive activities and actions. 

Constitutional limits apply to Congress’s oversight and investigative powers. This includes the protections of the First, Fourth, and Fifth Amendments but does not include the trial-related rights of the Sixth Amendment.

The Supreme Court on Oversight Limitations

Barenblatt v. United States: “Congress, in common with all branches of the Government, must exercise its powers subject to the limitations placed by the Constitution on governmental action,” including “the relevant limitations of the Bill of Rights”…

They are going to have to twist into pretzels to claim that, for example, the Trump family’s finances have anything to do with legislative purposes. They want to take on the role of the DOJ to investigate what they manufacture as potential crimes. I don’t think that is within the purvue of Congress. I imagine there will be battles going to SCOTUS over their “oversight.” They want to tie up as many effective people as possible with lawfare.
