Quinn Emanuel Urquhart & Sullivan, LLP

Alexander “AJ” Merton is Co-Managing Partner of Quinn Emanuel’s Washington, D.C. office. He is a seasoned trial lawyer and trusted advisor to companies, boards, senior executives, and senior government officials navigating congressional and government investigations, crisis management, tax controversies, and complex commercial litigation. His work frequently involves matters where criminal, civil, regulatory, and reputational exposure collide—and he is as effective in a courtroom as he is in the hearing rooms of Capitol Hill or marshaling clients through investigations by DOJ, the IRS, an inspector general’s office, or a congressional committee.

AJ maintains a robust and formidable congressional investigations practice. He has served as counsel to cabinet and sub-cabinet nominees in Senate confirmation hearings; represented and advised senior government officials facing congressional oversight inquiries; served as lead counsel in a bicameral antitrust investigation by the Senate and House committees on antitrust, with parallel investigations by the Department of Justice and the Department of Education; advised a major research university president in connection with high-profile congressional hearings; and represented multiple companies in matters before various Senate and House committees and subcommittees, including investigations involving antitrust, greenwashing, and national security-related claims. He brings to each of these engagements a practitioner’s understanding of how to manage testimony, document production, and public positioning across proceedings that move on different timelines, answer to different institutional interests, and carry distinct legal and reputational consequences.

Beyond Capitol Hill, AJ’s matters have included parallel criminal and civil enforcement proceedings; domestic and cross-border government investigations; multi-billion dollar tax disputes against the IRS and DOJ; ESG, climate change, and greenwashing litigation; trade secret cases; and complex commercial disputes involving RICO allegations, breaches of fiduciary duty, and fraud. He is a seasoned advocate for companies and individuals navigating simultaneous exposure across multiple enforcement bodies and jurisdictions.

AJ has been recognized by Lawdragon as a Global Leader in Crisis Management (2025, 2026), twice named The American Lawyer’s “Litigator of the Week” (2021, 2024), selected for Bloomberg Law’s “They’ve Got Next: The 40 Under 40” in White Collar, Government Investigations & Tax (2022), and ranked in The Best Lawyers in America: Ones to Watch for Litigation and Controversy—Tax (2023–2025). Prior to joining the firm, AJ was a trial attorney for the U.S. Department of Justice, Tax Division, where he began through the Attorney General’s Honors Program. While there, AJ was twice awarded the U.S. DOJ Tax Division’s Outstanding Attorney Award and represented the United States throughout multiple U.S. District and Bankruptcy Courts in tax controversy matters including aerospace asset and joint-venture valuation disputes, transferee liabilities, and government enforcement against attempts to evade or defeat federal taxes.

Before law school, AJ taught 7th through 12th grade argument and debate at a college preparatory school in San Jose, California.
