U.S. House Benghazi Panel Subpoenas Former Clinton White House Aide

Congressional investigators have issued a subpoena demanding that former Clinton White House adviser Sidney Blumenthal testify next month before the U.S. House of Representatives committee investigating the 2012 attack on U.S. diplomatic facilities in Benghazi, Libya.
The subpoena, a copy of which was made available to Reuters, demands that Blumenthal appear before the House committee on June 3 to give a deposition. The subpoena is dated Monday but carries a notation indicating an unnamed deputy U.S. marshal served it on Blumenthal's wife on Tuesday.
The copy of the subpoena contains no further details about the subject matter of the deposition.
More than two years ago, a set of emails sent by Blumenthal to Hillary Clinton while she served as secretary of state were posted on the Internet by a hacker who called himself Guccifer. Blumenthal did not work for Clinton when she was secretary of state and sent those emails as a private individual.
