The committee investigating Benghazi formally requested Friday that Hillary Rodham Clinton turn her email server over to an independent third party so it can be scrutinized to determine whether she and the Obama administration complied with open-records laws. Committee Chairman Trey Gowdy sent a letter to the former secretary of state’s personal lawyer making the request, which he said only comes after “exhaustive efforts” to get a look at her communications during the time of the 2012 terrorist attack on the diplomatic post in Libya’s second-largest city.
