Arnold & Porter's 11-partner securities enforcement and litigation practice frequently handles high-stakes federal and state class action securities and derivative actions, as well as SEC, DOJ, CFTC and FINRA investigations. Many of its cases concern allegations of market manipulation and insider trading. Veronica Callahan in New York leads the group. She led one of the most highly publicized securities fraud cases brought in recent years when she defended the founder of Infinity Q Capital Management. Key partner Kathleen Reilly was also involved in that case. Aaron Miner recently acted for Yelp Inc. in a class action alleging misrepresentations and omissions relating to retention levels for local advertisers. In Washington DC, up-and-coming partner Jane Norberg, former Chief of the Office of the Whistleblower for the SEC, and Daniel Hawke, former head of the SEC’s Market Abuse Unit, are the key contacts.
