Another 5,500 pages of Hillary Clinton's emails were released on Thursday, leaving the State Department short of a court-ordered quota for 2015, NBC News reported.
The emails were the most recent from the private server Clinton used during her time as secretary of state.
The State Department said that "the large number of documents involved and the holiday schedule" left it short of its target.
