A Democratic senator said he would indefinitely block President Bush’s nominee to become the C.I.A.’s top lawyer. “I’m going to keep the hold until the detention and interrogation program is on firm footing, both in terms of effectiveness and legality,” said Senator Ron Wyden of Oregon. Mr. Wyden said he was troubled that John Rizzo, who is the Central Intelligence Agency’s interim general counsel, did not object to a 2002 memo authorizing interrogation techniques that stop just short of inflicting pain equal to that accompanying organ failure or even death. Mr. Wyden also said he was concerned that an executive order issued last month by Mr. Bush did not clarify legal guidelines regarding detentions and interrogations.
