Greg Jaeger’s practice focuses in the areas of government contracts, export controls, international trade sanctions, government investigations and the Foreign Corrupt Practices Act (FCPA) and related anti-corruption laws. He counsels companies on legal issues involving export controls and US sanctions laws and regulations under the International Traffic in Arms Regulations (ITAR), Export Administration Regulations (EAR), and Office of Foreign Assets Control (OFAC) regulations. Mr. Jaeger also advises companies and investors on supply chain accountability and on national security reviews of foreign investments in the United States by the Committee on Foreign Investment in the United States (CFIUS).

Mr. Jaeger has over 20 years of experience in representing both foreign and domestic clients in government contracts matters. He provides counsel on a range of issues involving the award, formation and performance of government contracts and, in particular, assists companies in addressing the numerous government contracting issues that can arise in connection with M&A transactions. These issues can include contractual compliance and performance, novations, organizational conflicts of interest, procurement integrity, small business/socio-economic programs, subcontracts and teaming agreements, government rights in IP and technical data, suspensions/debarments, and terminations for convenience and default. He also works with the firm’s Real Estate Practice Group on GSA leasing issues.

Mr. Jaeger handles government contracts litigation, including pre- and post-award protests, claims and terminations, False Claims Act (FCA) matters, Fifth Amendment takings, and complex damages claims against the government. In addition to working as a trial and appellate lawyer in private practice, Mr. Jaeger served as a trial and appellate attorney for the United States Department of Justice in the Commercial Litigation Branch in Washington, DC, where he represented the United States and numerous Federal agencies in commercial litigation matters before the United States Court of Appeals for the Federal Circuit, the United States Court of Federal Claims and the United States Court of International Trade and was awarded a Special Commendation Award.

Mr. Jaeger’s previous experience as a trial attorney for the Justice Department enables him to provide clients with unique insight and capabilities in negotiating with, and litigating against, the government. He is well versed in all aspects of FCA litigation: from the defense of companies in the initial stages of an FCA suit, including responding to agency subpoenas and Department of Justice Civil Investigative Demands, conducting internal investigations regarding FCA allegations, strategically employing early motions practice regarding the unique elements of FCA claims, to dismissal of allegations asserted against a company. His experience also includes the conduct of, and the defense against, written discovery, fact and expert witness depositions and trial before the Court or jury.

In FCA cases that are initiated by private individuals (known as qui tam relators), Mr. Jaeger has litigated the unique issues that arise from these suits and in developing the particular defenses that the FCA statute provides against such suits. He has not only defended large corporate clients against both government-initiated FCA suits and qui tam suits, but has also prosecuted such suits on behalf of the Department of Justice. This experience on “both sides of the aisle” provides clients with unique insight and capabilities in defending against FCA allegations.

Mr. Jaeger also has trial and appellate experience in state court litigation, and in litigating complex commercial matters before various federal district and appellate courts, including the U.S. Supreme Court.

Mr. Jaeger has represented both foreign and domestic clients in export control and trade sanctions matters, including compliance with the International Traffic in Arms Regulations (ITAR), the Export Administration Regulations (EAR), the trade sanctions/embargo regulations administered by the Office of Foreign Assets Control (OFAC), the Anti-Boycott Regulations administered by the Department of Commerce and the Foreign Corrupt Practices Act. He also has worked with clients in resolving Committee on Foreign Investment in the United States (CFIUS) and national security issues. 

Mr. Jaeger’s experience in these areas includes compliance counseling and reviews, the development and implementation of compliance programs, classification and licensing issues, voluntary disclosures, due diligence reviews and investigations of individuals and corporate entities, conducting internal investigations and defending against government investigations. In the M&A arena, Mr. Jaeger has conducted dozens of due diligence reviews/investigations in each of the above areas, from both the buy and sell side.
