Mr. Blumenthal will answer questions about memos he drafted on Libya when Mrs. Clinton ran the State Department, Politico reported Friday.
"This appearance before the Select Committee on Benghazi involves a witness deposition, which is typically done in private," an advisory from the committee states, Politico reported.
The session will be closed to the media and the public.
Committee Chairman, Rep. Trey Gowdy of South Carolina, raised questions about Mr. Blumenthal's involvement in the State Department's response to the Benghazi attacks on Sept. 11, 2012. The Republican lawmaker did so after reviewing thousands of documents, which showed Mr. Blumenthal and the secretary traded frequent emails on the security and diplomatic climate in Libya before the attacks.
Mr. Blumenthal was not employed at the State Department when he drafted the memos but he was being paid by the Clinton Foundation at the time, Politico reported.
