Sen. Ron Wyden (D-OR) is on the Senate Select Committee on Intelligence which is (according to his website) “charged with overseeing and making continuing studies of the intelligence activities and programs of the United States Government. … The committee also oversees all United States intelligence activities to be certain that they conform with the laws and Constitution of the United States.”
Drop the senator a note and ask that he push the committee to investigate President Bush’s authorization of the NSA to spy on the United States without first obtaining warrants. While you’re at it, ask him if he was one of “leaders in Congress” Bush claims have been briefed “more than a dozen times” on this matter.
