Hillary Clinton's former chief of staff, Cheryl Mills, is asking a federal judge to order a conservative group not to release audio or video recordings of a deposition Mills is scheduled to give Friday about Clinton's use of a private email server during her tenure as secretary of state. Mills' attorneys filed a motion Wednesday afternoon saying they fear that the group that sought Mills' deposition in a Freedom of Information Act lawsuit, Judicial Watch, will use any recording to distort Mills' testimony and advance the group's anti-Clinton agenda.
