Senate members call for spy probe:
Republican Sens. Chuck Hagel of Nebraska and Olympia Snowe of Maine joined Democratic Sens. Carl Levin of Michigan, Dianne Feinstein of California and Ron Wyden of Oregon in calling for a joint investigation by the Senate Intelligence and Judiciary Committees into whether the government eavesdropped "without appropriate legal authority."
Several Republican and Democratic lawmakers have already backed a plan for a congressional hearing into the program, first revealed by The New York Times last week.
