Congressional Oversight and Investigations

When Congress has questions, how you answer shapes what comes next. We help you get it right.

Congressional oversight can reach any company holding federal contracts, receiving federal funding, or regulated by federal agencies. These proceedings move faster and more publicly than litigation.

When an inquiry comes, experienced counsel matters most in the first days, before positions are set.

Our Congressional Oversight and Investigations team has worked every side of the process. Holland & Hart’s Federal Affairs professionals have conducted oversight as senior congressional staff and responded to it as executive branch officials in both Democratic and Republican administrations. Our Government Investigations and White Collar Defense attorneys have led government inquiries as US Attorneys, federal prosecutors, and enforcement counsel. They have also defended clients when a congressional inquiry became something more.

This experience shapes our approach. We help clients see exposure before a committee acts, engage with staff and members to narrow inquiries, and judge when to push back. When responses are required, we make sure they are accurate, complete, and considered. We also prepare corporate executives for congressional testimony.

One team coordinates the legal, political, and communications response, from the first request through final resolution, including when a congressional inquiry runs alongside a DOJ, SEC, or state attorney general matter. One team. One strategy. One voice.

We represent public and private companies, trade associations, boards, and executives in any industry, with particular depth in mining, oil and gas, data centers, and other regulated sectors.

Congressional oversight is Congress’s authority to examine how federal agencies develop policy, spend federal funds, and carry out their responsibilities. It regularly extends to private companies, institutions, and individuals that those agencies regulate, fund, or work with.

A congressional investigation is a committee’s formal effort to gather information on a matter within its jurisdiction. It can involve letters requesting documents or communications, transcribed interviews with committee staff, subpoenas, public hearings, and, in some cases, referrals to the US Department of Justice or other agencies.

Our team has worked every side of congressional oversight: conducting it as committee staff, responding to it inside federal agencies, and defending clients when an inquiry escalated into a government investigation. Because one team handles all of it, clients are never coordinating three sets of advisors while a committee's clock is running.

There is no judge, no settled rules of evidence, and no fixed procedure; the committee sets the terms, the process is political as well as legal, and much of it plays out in public. Approaches that work in a courtroom or before an agency can backfire on Capitol Hill.

Anywhere from a few weeks to the life of a Congress. Most resolve within months at the letter or briefing stage, but an inquiry can be revived when leadership changes, so how it closes matters as much as how fast.

Yes. Federal contracts and funding, regulatory decisions, business relationships, and trade association membership can all bring a company into an inquiry, so the exposure is broader than many companies expect. A short assessment before a transaction, a policy fight, or a new Congress shows where that exposure is and how to reduce it.

A letter is a request, not a legal command, but declining to respond or responding thinly often leads to a subpoena, a public hearing, or both. The better question is how to respond in a way that narrows the inquiry rather than widens it.

Act promptly: preserve potentially responsive information, understand the committee’s authority, objectives, and deadlines, and assemble legal and communications counsel before engaging with committee staff. The first response sets the course for everything that follows.
