Nancy Mace - following in the media’s footsteps - guilty by allegations.
THE ONLY THING Congress should investigate is just units of the federal government as part of their oversight of the federal government.
They are not the police (the executive is), the prosecutor (the justice department is), or a court (the judiciary is). They have no Constitutional mandate to perform the powers of the executive or the judiciary.
They should limit themselves to referrals to the DOJ for any crimes alleged (ALLEGED) to have been violated by their own members or staff, and making formal inquiries with executive governments units on all other matters they want to see investigated, either by the DOJ or the inspectors general.
They should spend 100% less time on “investigations” and 100% more time on enacting the most basic legislative requirements; reforms of federal regulations, the federal budget and spending allocations, repeal of excessive federal regulations, and cutting back on and downsizing the federal bureaucracy and the legal requirements for that bureaucracy.
