The American Lawyer reports US Attorney Thomas O'Brien has taken on international drug cartels, some of the West Coast's toughest street gangs, and human smuggling rings. But now he has to do something that may be even more challenging: build a book of business.

Paul, Hastings, Janofsky & Walker announced Tuesday that O'Brien, who has been US Attorney for the Central District of California since 2007, will become a partner in the firm's Los Angeles office, where he will focus on white-collar cases.

"The people I met at Paul Hastings are top notch attorneys and I look forward to working with the firm to help them develop a white-collar practice in Los Angeles," says O'Brien, who was appointed US Attorney by President George W. Bush after more than two years as the office's criminal division chief.

He joins the firm Oct. 1.

The American Lawyer reports that months away from arguing a landmark securities fraud case before the US Supreme Court, Merck has passed lead counsel duties from Cravath, Swaine & Moore's Evan Chesler to Williams & Connolly, court records show.

Williams & Connolly partner Kannon Shanmugam, who argued eight cases before the high court during his four years with the US Solicitor's Office, will present Merck's case to the justices this fall. Shanmugam -- W&C's first lateral hire in 22 years when he joined the firm last year -- won six of those eight cases.

In this case, Shanmugam will argue to overturn an appellate ruling that allowed a securities fraud class action brought by Merck's shareholders to proceed.

Michael Waldron, also a partner, will work out of Patton Boggs' Dallas office.

Andreano advises settlement service providers through issues concerning the Real Estate Settlement Procedures Act, Truth in Lending Act, Equal Credit Opportunity Act, Fair Housing Act, Fair Credit Reporting Act, Home Mortgage Disclosure Act and the Gramm Leach Bliley Act.
