Kirkland & Ellis is picking up a team from Wilmer Cutler Pickering Hale and Dorr, including a practice leader who has represented former Trump campaign manager Paul Manafort and Facebook CEO Mark Zuckerberg.

Reginald Brown, the chairman of WilmerHale's financial institutions group and the vice chairman of its crisis management and strategic response group, is joining Kirkland's Washington, D.C., office on Tuesday along with three other partners, the firm announced Monday.

Brown, who headed WilmerHale's congressional investigations practice, led the firm's team preparing and guiding Zuckerberg through two days of hearings before Congress in April 2018, after Facebook acknowledged that up to 87 million of its users had their personal information harvested by Cambridge Analytica.

Manafort tapped Brown, a former associate White House counsel to President George W. Bush, amid investigations into Manafort's Russia ties by WilmerHale partner-turned special counsel Robert Mueller and House Democrats. Manafort swapped lawyers in August 2017; he was convicted of bank fraud, tax fraud and failing to disclose foreign bank accounts a year later.

In September, Brown was named to the board of directors of private equity giant The Blackstone Group Inc.

"Reg Brown is trusted by top global institutions and leaders to help them navigate challenges where the stakes couldn't be any higher," Jon Ballis, chairman of Kirkland's executive committee, said in a press release.

Accompanying Brown to Kirkland are Daniel Chaudoin, a former Securities and Exchange Commission official; Jeremey Dresner, who has represented major financial institutions in a variety of government hearings and investigations; and Daniel Kearney, a former legal adviser to U.S. Secretary of State Condoleeza Rice.

Kirkland touted the team's work for individuals and organizations in matters that involve high-stakes litigation, complex regulatory environments as well as ongoing public policy debates. Mark Filip, the head of Kirkland's government, regulatory and internal investigations group, called this a "strength-on-strength move."

Kirkland closed out 2019 as the highest-grossing firm in the United States, according to American Lawyer rankings, with more than $4 billion in annual revenue and profits per equity partner above $5.1 million.

The firm has pressed that financial advantage to pursue an aggressive lateral hiring strategy in recent years, luring new partners with expansive pay packages.

Washington-centered WilmerHale had revenue of $1.8 billion last year, with average profits of $2.3 million across its single-tier partnership, according to Am Law's rankings.

Brown, in a press release, said Kirkland "has a well-deserved reputation for excellence," adding that he would be working with old colleagues at the firm. He wasn't immediately available to comment.

A WilmerHale spokeswoman did not respond to a request for comment.
