Patton Boggs is in negotiations to purchase the Breaux-Lott Leadership Group

Washington’s biggest lobbying firm is on the verge of getting even bigger. Patton Boggs LLP, which rang up nearly $40 million in lobbying last year, is in negotiations to purchase the Breaux-Lott Leadership Group, according to sources familiar with the talks.

Breaux-Lott — named for its founders, former U.S. senators John Breaux (D-La.) and Trent Lott (R-Miss.) — already has a close relationship with the Patton Boggs behemoth, with the two firms operating in a “strategic relationship” for the past two years. Thomas Hale Boggs Jr., the larger firm’s chairman, has particularly close ties with Breaux, who left Patton Boggs to partner with Lott.

While Patton Boggs has long held the title as K Street’s largest and most influential lobbying firm, Breaux-Lott is a smaller, family-dominated operation that reported just less than $11 million in lobbying in 2009. The firm was formed in January 2008, shortly after Lott left the Senate, and includes both of the founders’ sons and a former Lott aide on its payroll.
