Former Homeland Security Chief of Staff and Federal Prosecutor Paul M. Rosen Joins Crowell & Moring as Partner

His practice will encompass government investigations, cybersecurity, and crisis management

Los Angeles – May 2, 2017: Crowell & Moring is pleased to announce that Paul M. Rosen, a former federal prosecutor who served as a senior government executive at the Department of Homeland Security, including chief of staff to former Homeland Security Secretary Jeh Johnson, has joined the firm’s Los Angeles office as a partner in the White Collar & Regulatory Enforcement, Privacy and Cybersecurity, and Government Contracts groups. With more than a decade of legal and policy experience across all three branches of the U.S. government, Rosen will focus his practice on government investigations, cybersecurity and data privacy, and crisis management.

Rosen will represent corporate and individual clients enmeshed in major controversies that involve government enforcement actions, internal investigations, and litigation in connection with criminal, civil, regulatory, administrative, transactional, and congressional matters.

“Paul’s understanding of government controversies – including investigations and prosecutions – and how to respond to them on behalf of clients is a significant asset for those facing all manner of legal crises,” said Angela Styles, chair of Crowell & Moring. “His experience in coordinating responses to national security incidents, including major data breaches, is precisely the insight our clients need amid the ever-present threat of cyberattacks. We are very pleased that Paul has joined our firm.”  

In his most recent role, Rosen managed for Secretary Johnson the operational, policy, and legal needs of the third-largest department in the Executive Branch, advising on a broad range of national security issues from counterterrorism, cybersecurity, border security, and aviation security to trade and travel, immigration and visa policies, CFIUS, and criminal law enforcement matters. In addition, Rosen has more than four years of experience as a prosecutor and counselor within the Department of Justice. Among his roles, he investigated and prosecuted nationwide, multi-jurisdictional financial fraud matters as a trial attorney for the Department of Justice’s Criminal Fraud Section. He also was counselor to Joseph R. Biden on the Senate Judiciary Committee.

"Paul is a superb addition to our outstanding white collar team at Crowell & Moring," said Daniel L. Zelenko, chair of the firm’s White Collar and Regulatory Enforcement Group. "With substantive experience as a federal prosecutor and key executive leadership roles at the DHS, he brings a unique mix of knowledge and relationships to help navigate our clients through any crisis. We are thrilled to have him on board."

“Paul is also well-equipped to handle corporate cybersecurity challenges,” said Jeffrey L. Poston, co-chair of the firm’s Privacy and Cybersecurity Group. “He has the experience to identify areas of potential exposure, assist clients navigate areas of government scrutiny, and coordinate incident response with federal and state law enforcement agencies.”

“Paul’s government leadership and his knowledge of the contracting industry will be a service to our clients,” said Daniel R. Forman, co-chair of the firm’s Government Contracts Group. “His senior executive experience at DHS in particular will add significant value to government contractors who do business with Homeland Security.” 

Rosen’s practice in Los Angeles will encompass a wide range of criminal, regulatory, and civil litigation matters, as well as governmental and internal investigations. Given his extensive government experience in Washington, Rosen will be in a unique position to advise clients across the United States, particularly those on the West Coast, that are dealing with looming government controversies.

“Crowell & Moring has an exceptional combination of terrific lawyers and superb practices in white collar, privacy and cybersecurity, and government contracts, and I am thrilled to join its partnership and further expand the firm’s West Coast presence in these areas,” Rosen said. “I am looking forward to helping clients, wherever they reside, craft innovative solutions to their most challenging problems.”

Rosen is the recipient of the DHS Distinguished Service Medal, the highest honor bestowed by the Secretary to recognize exceptional and transformational public service; the Director’s Distinguished Service Award from the Secret Service; and the Investigation Award of Excellence by the Council of Inspectors General on Integrity and Efficiency. He is a speaker at Harvard’s John F. Kennedy School of Government and the University of Southern California.

Rosen received his J.D., Order of the Coif, from the University of Southern California School of Law and his B.A., summa cum laude, from the University of Colorado at Boulder. He was law clerk to U.S. District Court Judge Gary Allen Feess of the Central District of California.
