(Reuters) - Congress has subpoenaed the emails of "close to a dozen" people who worked in the State Department for Hillary Clinton when she was secretary of state, the chairman of the U.S. House committee investigating the 2012 Benghazi attacks said on Thursday.
Representative Trey Gowdy, chairman of the Benghazi Select Committee, told Reuters these included aides to Clinton and perhaps "aides to aides."
"We sent a subpoena to the State Department for emails from a number of individuals within the State Department, other than Secretary Clinton," Gowdy, a Republican, said in a phone interview.
A New York Times report this month that Clinton had used a personal email account for government business while the chief U.S. diplomat from 2009 to 2013 has reinvigorated the committee's investigation into the Sept. 11, 2012, attacks that killed U.S. Ambassador Christopher Stevens and three other Americans.
Clinton, the front-runner for the Democratic presidential nomination in 2016 even though she has yet to formally declare her candidacy, has come under scrutiny from Republicans who accuse her State Department of failing to protect diplomatic personnel.
