(CNN) Former Democratic presidential nominee Hillary Clinton said Tuesday that President Donald Trump would have been indicted in the Mueller investigation if not for a long-standing Department of Justice rule that shields a sitting president from indictments.

"I think there's enough there that any other person who had engaged in those acts would certainly have been indicted," Clinton said at the Time 100 summit Tuesday. "But because of the rule in the Justice Department that you can't indict a sitting president, the whole matter of obstruction was very directly sent to the Congress."

The Justice Department, including special counsel Robert Mueller's team, has followed the Office of Legal Counsel's guidance from 2000 stating that "the indictment or criminal prosecution of a sitting President would unconstitutionally undermine the capacity of the executive branch to perform its constitutionally assigned functions."

Clinton pointed to the obstruction section of the redacted Mueller report released last week , saying it "could not be clearer" in compelling Congress to act.

"Basically what I thought it was saying is, 'Look, we think he obstructed justice -- here are 11 examples of why we think he obstructed justice, but we're under the control of the Justice Department, and their rule is you can't indict,' " she said.
