While Hillary Clinton speeds toward the Democratic presidential nomination, the investigation into her use of email continues. Alana Goodman offers an update for the Washington Free Beacon.

A watchdog group asked a federal judge on Tuesday to order court testimony from Hillary Clinton’s aides Huma Abedin and Cheryl Mills about Clinton’s use of a private email server.

Judicial Watch, which has been suing the State Department for public records from Clinton’s time as secretary of state, is also asking to depose State Department senior administrator Patrick Kennedy, technical aide Bryan Pagliano, and three other department officials.

U.S. District Court Judge Emmet Sullivan said last month that Judicial Watch could seek outside testimony and documents to help the court determine if Clinton’s use of a private email server was a deliberate effort to evade public records laws.

Although Judicial Watch has not asked to depose Clinton, it indicated that it might do so at a later date.

“Based on information learned during discovery, the deposition of Mrs. Clinton may be necessary,” the group said in its discovery plan filed on Tuesday. “If Plaintiff believes Mrs. Clinton’s testimony is required, it will request permission from the Court at the appropriate time.”

Judicial Watch said it would question Clinton’s aides about the creation and maintenance of her private email system, whether there were any inquiries about her use of the private server at the State Department, and how officials responded to these inquiries.

The group said it would also ask about “any instructions or directions given to State Department officials and employees about communicating with Mrs. Clinton and Ms. Abedin via email” and “the inventorying or other accounting of Mrs. Clinton’s and Ms. Abedin’s email upon their departure from the State Department.”
