Top officials with the National Archives and Records Administration were concerned that Hillary Clinton might attempt to take her State Department records with her to the Clinton Library in Arkansas while she was still in office, internal emails show.

Paul Wester, the archives’ chief records officer, said in December 2012 that he and other agency officials needed to “discuss what we know” about the State Department’s handling of Clinton records and map out a way to “delicately go about learning more,” according to documents obtained by the nonpartisan watchdog group Cause of Action and made public Thursday.
