The Intelligence Committee Hearing produced this interesting exchange:

A similarly revealing sparring session came when Senator Ron Wyden, Democrat of Oregon, pressed the intelligence officials about whether a controversial Pentagon data-mining program called Total Information Awareness had been effectively transferred to the intelligence agencies after being shut down by Congress.

Mr. Negroponte and the F.B.I. director, Robert S. Mueller III, both said they did not know. Then came the turn of Gen. Michael V. Hayden, who headed N.S.A. for six years before becoming the principal deputy director of national intelligence last spring.

“Senator,” General Hayden said, “I’d like to answer in closed session.”
