In response to a question from Democrat Joe Manchin and Kristin Sinema, and Republicans Lisa Murkowski, and Susan Collins about whether the White House would assure the Senate that it would not allow private citizens to conduct foreign policy, White House lawyer Patrick Philbin stepped in it, and Rep. Adam Schiff pounced. Philbin answered "I just want to make clear that there was no conduct of foreign policy being carried on here by a private person."
That was all the opening Schiff needed. "We have just heard a breathtaking admission by the President's lawyer," he said. "What the President's counsel said was that no foreign policy was being conducted by a private person here. That is Rudy Giuliani was not conducting U.S. foreign policy. Rudy Giuliani was not conducting policy. That is a remarkable admission," Schiff continued. They have suggested, he said, that "this is a policy issue," about burden-sharing or corruption, but "they have no acknowledged that this was not about policy. […] This was not policy conducted by Mr. Giuliani."
"They have just undermined their entire argument," he added. "If Giuliani wasn't there conducting foreign policy, it must have been a "personal political errand."
