Surprise: Not all of Hillary's Libya emails were turned over to the Benghazi Committee

House GOP Benghazi investigators have discovered additional Libya communications between Sidney Blumenthal and former Secretary of State Hillary Clinton, a congressional source told POLITICO — suggesting that either the State Department or the 2016 Democratic presidential contender withheld correspondence the panel had subpoenaed.

Blumenthal — a longtime Clinton family friend who is set to testify before the committee behind closed doors Tuesday morning — recently gave the House Select Committee on Benghazi his Libya-related emails after the panel had quietly subpoenaed them.

Among those were several emails concerning Libya between Blumenthal and Clinton that had not been previously turned over by State. Clinton has said she gave all her work-related correspondence, kept on her personal email server, to the State Department. State was then tasked with going through the emails and giving the panel relevant correspondence. Department officials turned up about 300 emails related to Benghazi.
