Republican Lawyers Representing Politicians and Government Officials (Republicans & Democrats) Targeted in Federal Investigations and Law Enforcement Matters

In today’s Republican-centered political environment, many politicians and government officials are facing unprecedented scrutiny. While federal investigations into politicians and government officials were once reserved for cases involving major allegations that captured the nation’s attention, today they are a regular occurrence; and, with increasing frequency, they are highly politicized in nature. From congressional committees to the U.S. Department of Justice (DOJ) and U.S. Department of Homeland Security (DHS), politicians and government officials can face scrutiny from a variety of sources, and this scrutiny can have serious political and legal ramifications.

How We Can Help

We represent politicians (both Republicans and Democrats) and government officials as defense counsel in all types of federal investigations and law enforcement matters. If you are facing federal scrutiny (or if you are concerned about facing scrutiny), we encourage you to contact us promptly. The sooner you engage our firm to represent you, the more we can do to help. If the investigation has not yet been publicized, we may be able to keep it confidential; and, regardless of the circumstances, we can intervene in the process to begin steering it toward a favorable resolution under the circumstances at hand.

Some examples of matters we handle for politicians and government officials include:

Campaign Finance Matters

Candidates, elected officials who are running for reelection, and other individuals involved in the election process can face scrutiny in the area of campaign finance. Several federal laws play a role in restricting the sources of campaign funds in federal elections, all with the ultimate goal of preserving our democracy. This includes well-known laws such as the Federal Election Campaign Act (FECA) and Bipartisan Campaign Reform Act (BCRA).

But while these laws may be well-known, they are also frequently misunderstood. As a result, mistakes are common. In some cases, defending against allegations of campaign finance violations is a matter of demonstrating that the government’s allegations are misguided. But in others, politicians’ and government officials’ defense strategies must focus on convincing the DOJ that any mistakes were inadvertent—and, as such, do not merit criminal prosecution.

Congressional Investigations

Since the highly publicized hearings of the Select Committee to Investigate the January 6th Attack on the United States Capitol in 2023, congressional investigations have become increasingly common as a tool for both protecting our democracy and political gain. While most congressional investigations receive far less publicity, these investigations can still present significant risks for politicians and government officials–and those targeted by congressional committees must be prepared to defend themselves by all means available.

We represent politicians and government officials in all aspects of congressional investigations involving all standing, special, and select committees. This includes everything from managing our clients’ subpoena responses to representing our clients on Capitol Hill.

Criminal Investigations

If you are facing a federal criminal investigation as a politician or government official, it is imperative that you engage defense counsel promptly. The clock is ticking; and, the longer you wait, the more difficult it will become to assert a successful defense. Our former federal prosecutors and investigative agents have significant experience on both sides of high-stakes and high-profile criminal cases, and we have had significant success securing favorable results for our clients during government investigations, in grand jury proceedings, and both before and during trial.

Election Law Matters

From Congress to the Federal Election Commission (FEC), several federal authorities investigate and assist in the prosecution of federal election crimes. Civil allegations under FECA and other applicable laws are common as well. While civil allegations do not present the risk of incarceration (at least not immediately), they nonetheless present risks for significant financial liability and reputational harm.

At Oberheiden P.C., we have significant experience defending politicians and government officials in federal election law matters. Whether a congressional committee or the FEC has initiated an investigation on its own accord or is acting on information from a political adversary or watchdog organization, we can get to the bottom of the allegations at issue and execute a strategic defense on your behalf.

Immigration Law Matters

We have recently seen an increase in raids, investigations, and prosecutions targeting politicians, government officials, and others under U.S. immigration laws. These include, but are by no means limited to, efforts to target leaders of so-called sanctuary cities. Many of these cases involve allegations under 8 U.S.C. Section 1324, which prohibits “harboring” undocumented foreign citizens (a term which is very broadly defined), among other offenses.

We expect to see a significant increase in these cases in the years following the 2024 election–and, as of early 2025, we are seeing an increase in notable (and highly publicized) cases already. If you are being targeted for your involvement in any immigration-related matter, we can defend you against any charges that may be forthcoming.

Public Corruption and Bribery Allegations

Allegations of public corruption and bribery present financial and reputational risks for politicians and government officials as well. This includes allegations of offering, soliciting, accepting, and paying kickbacks and other prohibited forms of monetary compensation. It also includes accepting campaign contributions in exchange for political favors, whether directly or indirectly, and whether from entities located domestically or abroad.

These also tend to be highly complex matters, and presenting an effective defense requires an in-depth understanding of how the relevant laws and regulations apply to the specific circumstances in question. If you are facing accusations of being a corrupt politician or government official, we can help set the record straight, and we can use our experience in these cases to assert all available defenses.

Violations of Executive Orders

We are seeing many cases involving allegations of violating executive orders as well. These allegations are being used to target politicians and officials at all levels of government, as well as other individuals in both the public and private sectors. The current administration has made clear its intent to vigorously enforce the President’s executive orders–pursuing formal charges and terminating positions within the federal government as deemed warranted.

Our lawyers are available to represent politicians, government officials, and other individuals in these matters. From defending against unwarranted allegations and personnel actions to challenging the legality of Executive Orders themselves, we are prepared to protect our clients’ interests by all means available.

Tax, Securities, and Other Federal Investigations

In addition to investigations and prosecutions involving allegations that are specific to the political sector, we also defend politicians and government officials who are facing other types of allegations. While these allegations are often part and parcel of politically motivated inquests, we see stand-alone investigations into politicians’ and government officials’ affairs as well. This includes investigations into alleged tax law violations, securities law violations, and other federal offenses—most (but not all) of which are financial in nature.
