Washington - Congressional investigators have issued a subpoena demanding that former Clinton White House adviser Sidney Blumenthal testify next month before the US House committee investigating the 2012 attack on US 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 US 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.
