You don’t need a subpoena to get the senior senator from Pennsylvania talking. From today’s New York Times:
Senator Arlen Specter, Republican of Pennsylvania, said that in one strategy session Mr. Bush told the senator he could not be identified as publicly supporting the Senate bill, which sought to tighten border control but also give illegal immigrants a chance to become citizens after paying fines. “Don’t quote me, Arlen,” Mr. Specter recalled the president saying, implying that Mr. Bush had spoken approvingly of the bill.
Pretty sleazy behavior, I’d say. Good thing Specter isn’t a journalist.
