Megan Crowley is a nationally recognized litigator who represents clients in complex, high-stakes cases at the intersection of law, government, and policy. As Co-Chair of Covington’s Government Litigation practice, she combines strategic foresight with public-sector experience, having previously litigated high-impact constitutional, statutory, and administrative law cases at the U.S. Department of Justice.

For more than five years, Megan has co-led Covington’s representation of TikTok in litigation concerning privacy, data security, and government regulation—some of the most consequential technology cases of the past decade. In 2020, she co-led Covington’s successful challenge to the Executive Order seeking to ban TikTok’s operations in the United States. In 2023, she and the team obtained a preliminary injunction blocking Montana’s statewide ban on TikTok—the first ruling of its kind. Since 2024, Megan has continued to co-lead Covington’s representation of TikTok in matters arising under the Protecting Americans from Foreign Adversary Controlled Applications Act, including proceedings before the D.C. Circuit and the U.S. Supreme Court, as well as related issues critical to the platform’s ongoing U.S. operations.

Megan has also achieved significant victories for other clients facing complex regulatory and constitutional challenges. She played a pivotal role in Covington’s successful representation of Xiaomi Corporation in overturning a Department of Defense designation that would have barred the company from U.S. financial markets, and has represented major global companies in administrative and appellate litigation involving data security, government regulation, and consumer protection.

In addition to her federal work, Megan has defended clients in State Attorney General enforcement actions. She delivered the winning argument that led to the complete dismissal of an Indiana Attorney General consumer protection action—one of several matters in which she has successfully opposed novel applications of state enforcement authority.

Beyond the courtroom, Megan advises clients on constitutional and administrative law issues, regulatory compliance, and emerging legislative frameworks governing online platforms. Her practice also encompasses litigation under Section 230 of the Communications Decency Act, the Administrative Procedure Act, the Electronic Communications Privacy Act, and the First Amendment.

Her achievements have earned broad recognition. The American Lawyer named her “Litigator of the Week” for her successes, and Law360 has recognized her as a Rising Star in Cybersecurity & Privacy.

Megan maintains a robust pro bono practice, focused on civil rights litigation. She played a central role on the team representing the University of California in its challenge to the government’s rescission of the Deferred Action for Childhood Arrivals (DACA) program, obtaining a nationwide injunction and, ultimately, a 5-4 victory in the U.S. Supreme Court.
