WASHINGTON (AP) — A federal judge said Wednesday he may order Democratic presidential front-runner Hillary Clinton to testify under oath about whether she used a private email server as secretary of state to evade public records disclosures. U.S. District Court Judge Emmet G. Sullivan signed an order granting a request from the conservative legal advocacy group Judicial Watch to question six current and former State Department staffers about the creation and purpose of the private email system. At issue is whether the State Department conducted an adequate search of public records in response to a Freedom of Information Act request filed by Judicial Watch in 2013 seeking records related to Abedin's outside work as a paid consultant for the Clintons' charitable foundation and a financial advisory firm with ties to the former first couple. In response to public records requests, the State Department has released more than 52,000 pages of her work-related emails, a small percentage of which have been withheld because they contain information considered sensitive to national security.
