Rep. Adam Schiff , Calif., the ranking Democrat on the Intelligence Committee, said the panel was aware that Yates "sought permission to testify from the White House. Whether the White House's desire to avoid a public claim of executive privilege to keep her from providing the full truth on what happened contributed to the decision to cancel today's hearing, we do not know. But we would urge that the open hearing be rescheduled without delay and that Ms. Yates be permitted to testify freely and openly.''
