In Washington, Attorney General Alberto Gonzales left open the possibility Wednesday that the Bush administration’s warrantless domestic spy program is more extensive than has been acknowledged. In a letter to senators reported in the Washington Post, Gonzales attempted to clarify testimony he gave before the Senate Judiciary Committee last month. During that testimony, Gonzales said that the program was all that had been authorized by President Bush. But in Tuesday’s letter, Gonzales, wrote: “I did not and could not address … any other classified intelligence activities. I was confining my remarks to the Terrorist Surveillance Program as described by the President.” Bruce Fein, a former government lawyer who served under three Presidents, said: “It seems to me he is conceding that there are other NSA surveillance programs ongoing that the president hasn’t told anyone about.”
