A federal judge has okayed depositions of eight people about Hillary Clinton's use of a private email server as secretary of state – and the Democratic presidential front-runner could ultimately be grilled as well, a Judicial Watch official tellsIn an interview Friday with "Newsmax Prime" host J.D. Hayworth, Chris Farrell, director of research and investigations for the conservative watchdog group, said federal Judge Emmet Sullivan is "fed up."Judicial Watch's original lawsuit sought information about the emails of Clinton's top aide Huma Abedin, but has since moved onClinton's use of the private server, which critics say may have compromised national security."We've been authorized by the court to depose eight different characters around Mrs. Clinton both current and former government officials at the State Department," Farrell said. "We reserve the right and the court has granted us the ability to go back to the judge once we've completed the eight depositions to ask to interview Mrs. Clinton as well."Watch Newsmax TV onandGet Newsmax TV on your cable system —Sullivan's decision, according to Farrell, was fueled by his growing impatience with the State Department."From the bench he made reference to a drip, drip, drip of never ending, never changing declarations from the State Department as to what was being done, what was discovered, what wasn't and so he became quite frustrated with their never-ending stories," Farrell said.Farrell added that within the conservative group, there's little confidence in the Obama administration's Justice Department about the outcome of the current FBI investigation of the email issue."It's a political question" with respect to Attorney General Loretta Lynch deciding to prosecutor Clinton should the FBI probe find criminal wrongdoing."She's a political appointee, she's an ideologue, an Obama loyalist," he said. "So even if [FBI Director James Comey] had the stomach to go forward and really issue an ultimatum to the attorney general about going forward, it's not his call, it's the attorney general's call."
