special counsel mueller. mueller keeps asking for his investigation to be expanded and rosenstein keeps expanding it. jeff sessions rekiewlsed himself on matter involving the campaign. rosenstein does not have the power outside of the recusal that sessions gave to expand mueller's investigation. he's not the attorney general when it comes to tax issues or whether someone failed to file as a foreign agent under the foreign acts act. rosenstein doesn't have the constitutional authority to be attorney general for all these other matters. jesse: we do know rosenstein was involved in signing off on the warrants that were in front of the fisa court because they kept on being renewed under james comey. there is a great piece out here
