Patton Boggs will close its Newark office after the firm lost almost $12 million there last year after insurance work arising from the Sept. 11 attacks dried up, according to Edward Newberry, Patton Boggs’ managing partner.

Newberry said in an interview with The National Law Journal Monday that the firm announced the closure to partners at a monthly meeting on Feb 20. The closure of the New Jersey office was first reported by POLITICO on Monday.
