Barnett led the antitrust division for three years, working on matters like the Delta-Northwest merger and Google’s ill-fated joint advertising agreement with Yahoo. Barnett resigned in mid-November.
Barnett first joined Covington in 1990. He spent 14 years at the firm, rising to become one of several vice chairs in its antitrust group.
In April 2004, Barnett left Covington to become deputy assistant attorney general for antitrust. He was elevated to acting assistant attorney general in June 2005, and was confirmed by the Senate to permanently fill the role in February 2006.
Under Barnett’s watch, the antitrust division secured more than $2 billion in criminal fines against 50 corporations and 91 individuals. That includes one of the largest antitrust settlements in US history, when Barnett’s division extracted $504 million from four international airlines to settle air cargo price-fixing charges.
Washington, DC’s Covington had gross revenues of $467 million and profits per equity partner of $1.175 million in 2007.
