President Obama says he's confident his new proposal on National Security Agency spying and retention of telephone data will allow the U.S. to deal with the dangers of terrorism. 

During a news conference today at the Nuclear Security Summit in the Hague, Obama said because of the revelations of widespread NSA spying, the U.S. must win back the trust of ordinary citizens and foreign governments. 

The President is expected to ask Congress to end much of the government's collection and holding of phone data and records.
