WASHINGTON (AP) — The head of the Senate Intelligence Committee is concerned about the idea that data from government phone surveillance might be stored by others.

Sen. Dianne Feinstein tells NBC's "Meet the Press" that such a move would be difficult because the purpose of the program is to provide instantaneous information in order to disrupt a terrorist plot that might be underway.

Feinstein says she doesn't think the National Security Agency surveillance will be shut down despite its critics. The California Democrat points to President Barack Obama's desire to maintain its capability.

Republican congressman Mike Rogers chairs the House Intelligence Committee. Rogers says he too has concerns about changing the NSA program. But he says he agrees with Obama that it's legal and proper.
