Obama pledges more oversight of NSA surveillance

President Barack Obama says he'll work with Congress to change the oversight of some of the National Security Agency's controversial surveillance programmes and name a new panel of outside experts to review technologies.
Obama says he wants to work with Congress to insert an opposing voice into arguments before the secret court that considers and approves massive government surveillance efforts.
The court currently hears only from Justice Department officials who want the surveillance approved.
The secret court and other surveillance programmes have been under scrutiny since NSA leaker Edward Snowden revealed classified programmes in June.
The government has defended these programmes as necessary to prevent terror attacks.

Speaking to reporters, Obama says the government can and must be more transparent in how it conducts surveillance.
