Wednesday morning, Robert Mueller spoke at the Justice Department, announcing the end of his two-year appointment as special counsel overseeing the Russia investigation.

Mueller re-emphasized the report's findings, and explained that a longstanding Department of Justice policy prohibits the indictment of a sitting president, and therefore charging the president with a crime was not an option.

"The opinion says that the Constitution requires a process other than the criminal justice system to formally accuse a sitting president of wrongdoing," Mueller said.

In other words, ball's in your court, Congress.
