LOUISVILLE, Ky. (AP) -- U.S. Sen. Rand Paul is calling into question the effectiveness of the government's sweeping surveillance of U.S. communications to thwart terror plots.
The Kentucky Republican said Friday he believes the government can be effective in catching would-be terrorists by obtaining warrants to review records.
Paul says he doubts that tracking programs by the National Security Agency have been responsible for catching terrorists.
His comments follow claims by U.S. intelligence officials that the NSA's data-collection programs thwarted at least 50 terrorist plots in the U.S. and more than 20 other countries. They said an estimated 10 to 12 of those plots were directed at the U.S.
Paul says he has lost confidence in the credibility of the nation's intelligence community.
The senator made the comments during a stop in Louisville.
