The committee wants documents that might shed light on internal squabbles within the administration over the legality of the program, said a congressional official speaking on condition of anonymity because the subpoenas had not been made public.
Leahy's committee authorized the subpoenas previously as part of its sweeping investigation into how much influence the White House exerts over the Justice Department and its chief, Attorney General Alberto Gonzales.
The probe, in its sixth month, began with an investigation into whether administration officials ordered the firings of eight federal prosecutors, for political reasons.
But with senators of both parties already concerned about the constitutionality of the administration's efforts to root out terrorism suspects in the United States, the committee shifted to the broader question of Gonzales' stewardship of Justice and, in particular, his willingness to permit the wiretapping program.
