The Obama administration on Thursday defended the National Security Agency’s use of a secret court order to collect telephone records from millions of Verizon customers.

The NSA has been collecting Verizon’s records on millions of calls since April 25, according to the court order.

The information provided to the NSA did not include the content of conversations or customers’ identities but covered telephone numbers used and the length of calls.

An administration official defended the collection of data as a “critical tool in protecting the nation from terrorist threats to the United States,” and leaders of the Senate Intelligence Committee said their colleagues were informed of the practice. They also said it had been continuing since 2007, when it was launched under the Bush administration.
