We all know that, globally, the unholy Dentons/Dacheng merger created a firm with approximately 280 million attorneys. But what’s the biggest law firm in the United States?
Late last night, while you were fast asleep still in the office, Law360 released its master list of the top 400 law firms in the U.S. by size.
America’s next president Donald J. Trump will be happy to learn that he’s represented by the biggest firm around. Jones Day tops the list with 1,684 attorneys. This vaults them past last year’s champion Morgan Lewis, who at the time was still digesting the carcass of Bingham it brought on. Morgan Lewis fell to third this year.
