“Those are the first two phases” of Nunes’ multipart inquiry, a senior investigator said. “In phase three, the involvement of the intelligence community will come into sharper focus.”

The aide, who spoke only on condition of anonymity, said Nunes will focus on Brennan as well as President Obama’s first CIA director, Leon Panetta, along with the former president’s intelligence czar, James Clapper, and national security adviser, Susan Rice, and security adviser-turned U.N. ambassador Samantha Power, among other intelligence officials.

“John Brennan did more than anyone to promulgate the dirty dossier,” the investigator said. “He politicized and effectively weaponized what was false intelligence against Trump.”
