Two weeks after Attorney General Michael Mukasey tearfully told a San Francisco audience the Sept. 11 terrorist attacks could have been prevented if the government had been able to wiretap a phone call from Afghanistan, the Justice Department is still trying to explain what he meant, and a congressional leader is demanding answers.
Among the questions posed by House Judiciary Committee Chairman John Conyers, D-Mich., to Mukasey is whether any such phone call actually occurred and, if so, why the government wasn't able to use its legal and technological powers to monitor it.
The attorney general, speaking to the Commonwealth Club on March 27, defended President Bush's program of wiretapping calls between Americans and suspected foreign terrorists without court authorization and said no warrant should be needed to eavesdrop on a phone call from Iraq to the United States.
