A federal judge cleared the way Wednesday for lawyers from a right-wing watch-dog group to take sworn testimony from top Hillary Clinton aides and opened the door for the group to seek an interview with Clinton herself later. But while the ruling is another political blow for the Clinton campaign, legally the former Secretary of State can thank one of her predecessors, Henry Kissinger, and former Supreme Court Chief Justice William Rehnquist, for providing her with a robust defense in a similar case more than 35 years ago. The depositions of Clinton’s aides are to take place over the next eight weeks as part of a long-running Freedom of Information Act (FOIA) suit brought by the group, Judicial Watch.
