Special Counsel Robert Mueller is set to testify before the House Judiciary and Intelligence Committees on Wednesday about his two-year investigation into 2016 Russian election interference. The Justice Department sent Mueller a letter on Monday telling him to limit his testimony so it remains "within the boundaries of your public report, because matters within the scope of your investigation were covered by executive privilege, including information protected by law enforcement, deliberative process, attorney work product, and presidential communication privileges." Rep. Jerrold Nadler (D-N.Y.) told Fox News' Chris Wallace on Sunday that Democrats will ask very specific questions about obstruction of justice. Mueller has previously said the report "speaks for itself."
