The White House is claiming it has already reformed some surveillance practices in the wake of the revelations by whistleblower Edward Snowden. On Tuesday, administration officials said an internal review has led to specific changes, without disclosing details. It is rumored President Obama will order an end to the National Security Agency’s spying on foreign leaders, yet no formal announcement has been made. At the White House, Press Secretary Jay Carney said the administration is awaiting the findings of a separate review.

White House Press Secretary Jay Carney: “What we’ve made clear is that we are undertaking a review of our activities around the world, with a special emphasis on examining whether we have the appropriate posture when it comes to heads of state, examining how we coordinate with our closest allies and partners, and examining what further guiding principles or constraints might be appropriate for our efforts.”
