UNDATED -- There is new information tonight on the government's secret surveillance program.
Leaders on Capitol Hill grilled the director of the NSA about collecting millions of phone records from Americans.
They wanted to know if the program really prevents terrorism.
The director said another classified program prevented an attack on New York's subway system.
He's promised to declassify more information. But he's also warned that a lot will remain secret.
