text: CEI General Counsel Sam Kazman said, "CEI is going forward with our motion for sanctions because Walker's withdrawal only strengthens our claim that this subpoena was a constitutional outrage from the very beginning, violating our right to free speech and our donors' right to confidentiality, and threatening the right of all Americans to express views that go against some party line. This subpoena was an abuse of process, plain and simple, and we're determined to see that Walker faces sanctions for his illegal actions that he refuses to recognize."
