Justice Department officials have reportedly told former Special Counsel Robert Mueller that the department expects him to limit his congressional testimony on Wednesday to already-public information from his office's report on its investigation into 2016 Russian election interference, Politico reports. Any material beyond the public findings is being considered "presumptively privileged."

However, both the White House and the Justice Department are expected to refrain from placing lawyers in the room during the House Judiciary and Intelligence Committee hearings, leaving Mueller to "police" himself.

The Trump administration doesn't seem too worried about that — Mueller is known for sticking to the rules and has previously said that the report is his testimony, so it was always unlikely that he'd go off script.

"[The report] contains our findings and analysis, and the reasons for the decisions we made," Mueller said in May. "We chose those words carefully, and the work speaks for itself."

All of this could prove a hurdle for Democrats on the panels, who are hoping to glean new information from the now-private citizen. But Politico reports that some Democrats have said that even if Mueller simply reads the report word-for-word, it would help "educate the American public" about President Trump's conduct during the Mueller's probe.
