About The Lenzner Firm

In today’s environment, where litigation, government enforcement, and regulatory scrutiny are often accompanied by intense media scrutiny and reputational risks that can spread online overnight, clients need a lawyer who can win in court while successfully navigating these secondary risks.  The Lenzner Firm combines years of experience in litigation with unrivaled fact-finding capabilities and firsthand experience in media relations to help clients prevail in adversarial disputes, mitigate risk, and solve complex problems.

The Lenzer Firm,  P.C. was founded by Terry F. Lenzner (now retired), who previously served as Assistant Chief Counsel to the Senate Watergate Committee. Prior to establishing the firm, Lenzner was a trial attorney in the Civil Rights Division of the U.S. Department of Justice, a federal prosecutor in the U.S. Attorney’s Office for the Southern District of New York, and an attorney at other prominent Washington, D.C. law firms.

Drawing on his experience at the U.S. Department of Justice, the White House, the New York County District Attorney’s Office, and in private practice, Arun G. Rao directs due diligence and corporate internal investigations, advises clients on crisis and risk management, handles white-collar matters, and leads business development initiatives.

Prior to joining The Lenzner Firm, Rao served as the Chief of the Southern Division of the U.S. Attorney’s Office for the District of Maryland, located in Greenbelt, Maryland.  In that capacity, he supervised federal prosecutors assigned to criminal cases in a geographic area with a population of more than two million people.  In March 2017, the Montgomery County Chamber of Commerce presented the office with the Public Safety Government Partner of the Year award, and in May 2017, the United States Secret Service Washington Field Office recognized Rao for his leadership.

While at the U.S. Department of Justice, Rao was involved in a wide variety of complex and high profile criminal cases.  Among the matters he handled was the prosecution of a former supervisory archivist of the National Archives.  At the conclusion of that case, the National Archives Office of Inspector General recognized Rao for assisting in the recovery of thousands of stolen historic artifacts.  Rao also participated in a long-term public corruption investigation involving the payment of bribes to elected officials in Maryland, including to members of the Prince George’s County Council and the Maryland House of Delegates.  The investigation and subsequent prosecutions led to widespread calls for ethics legislation, and the Maryland General Assembly later passed the Public Integrity Act of 2017, which the Governor of Maryland signed into law in April 2017.

Rao also served as a Deputy Associate Counsel in the Office of the White House Counsel from 2012 to 2013.  While at the White House, he drafted memoranda for review by President Barack Obama, the Chief of Staff, and senior advisors, identifying legal, ethical, and policy issues uncovered while vetting executive branch nominees, including candidates for the Cabinet.

Rao joined the U.S. Department of Justice in 2007 as an Assistant U.S. Attorney in the U.S. Attorney’s Office for the Western District of Tennessee, in Memphis, Tennessee.  He has briefed and argued cases before the United States Courts of Appeals for the Fourth and Sixth Circuits.  Earlier in his career, Rao was an Assistant District Attorney in the New York County District Attorney’s Office, serving under former District Attorney Robert M. Morgenthau.  Before becoming a prosecutor, he was an associate at Cravath, Swaine & Moore LLP.

Rao graduated with high honors from the University of Virginia in 1998. He received his J.D. in 2001 from New York University School of Law, where he was a member of the Moot Court Board. He clerked for the Honorable Julia Smith Gibbons of the U.S. Court of Appeals for the Sixth Circuit.
