I thought Michael didn't know that the senate hearing was up and running that Cicci had testified or Geary's question to him and his reply: "I never talked to him,"
Michael did know about Cicci's testimony. "I never talked to him" tricked Michael into believing that the subcommittee had no one who could testify that they gotten a direct order--and that he could safely lie under oath and deny all the accusations leveled against him.
