House Intelligence Committee Chairman Mike Rogers (R-Mich.) said Thursday that the National Security Agency’s monitoring of Verizon customers has stopped at least one major terrorist attack in the United States.

Rogers defended the program, according to the Washington Post, saying:

“Within the last few years, this program was used to stop a terrorist attack in the United States.  We know that. It’s important. It fills in a little seam that we have…And it’s used to make sure that there is not an international nexus to any terrorism event if there may be one ongoing.  So in that regard, it is a very valuable thing.”

Mike Rogers: NSA Monitoring Verizon Thwarted a Major Terrorist Attack

Rogers said he is working on declassifying the details of the attack, but cannot provide more information at the present time.

The Michigan congressman is only one of many lawmakers on both sides of the aisle to defend the government’s order that “telephony metadata” on all Verizon calls within the United States and from foreign countries into the United States be provided to the NSA.

The Obama administration and leaders from both the House and Senate Intelligence Committees have argued that the practice makes Americans safer, and that law-abiding Americans don’t have “anything to worry about,” in the words of South Carolina Senator Lindsey Graham.

Harry Reid (D-Nev.) said “everyone should just calm down” about the news.
