From Business Insider:

But Paul Rosenzweig, a former federal prosecutor and former deputy assistant secretary for policy at the Department of Homeland Security, told CNN there is a precedent for releasing grand-jury information from a criminal investigation when it’s in the public’s interest.

“There are procedural steps that need to be taken in order to secure the approval of the courts to give … grand jury material,” Rosenzweig said. “But that’s precisely the step that [former independent counsel] Ken Starr took in order to provide material to Congress, and that’s precisely the step that [former Watergate special prosecutor] Leon Jaworski took.”

“What’s different here is the apparent decision … of the attorney general not to take the same step that has been taken in the past,” Rosenzweig added. “Namely, to make as much of the grand jury information as is possible available to Congress for its consideration of its own oversight responsibilities.”
