Robert Mueller's grand jury is still working 'robustly' even after special counsel submitted final report to Justice Department

The federal grand jury in Washington, D.C., that special counsel Robert Mueller was using for his investigation is still working "robustly" even after Mueller submitted his final report about his probe to the Justice Department, a prosecutor said at a court hearing Wednesday. That revelation means that even as Mueller closes up the special counsel's shop after two years of work, there remains a chance that the grand jury he had used might issue further indictments.
