The AP story quote of Rosenstein:
Deputy Attorney General Rod Rosenstein’s comments at an event come as Mueller’s Russia probe winds down and as there is debate about what information should be made public at the end, particularly about individuals who were investigated but not charged.
Rosenstein did not discuss Mueller’s work in detail and did not suggest his comments about transparency were specifically about the special counsel’s investigation. But he made several remarks that could be interpreted as setting the stage for the Justice Department to not disclose as much about the investigation, and about the actions of President Donald Trump, as Democrats in Congress and many in the public might want.
“There’s a knee-jerk reaction to suggest that we should be transparent about what we do in government,” Rosenstein said. “But there are a lot of reasons not to be transparent about what we do in government.”
