Rudy Giuliani says Robert Muellers team has concluded it cant indict a sitting president
All they get to do is write a report, Mr. Giuliani told CNN. They cant indict. At least they acknowledged that to us after some battling, they acknowledged that to us.
The conclusion is likely based on Justice Department guidelines and not a result of evidence gathered by Mr. Muellers team, CNN reported.
The Justice Departments Office of Legal Counsel has held since the Nixon administration that a sitting president cannot be indicted, and the position was reaffirmed in the Clinton administration. It has never been tested in court, however.
Mr. Muellers team declined comment when contacted by CNN.
