Monitoring the records of as many as a billion phone calls, as some news reports have suggested, is no modest invasion of privacy. It is an extraordinary invasion of privacy. We fought a revolution over issues like generalized warrants, where soldiers would go from house to house, searching anything they liked. Our lives are now so digitized that the government going from computer to computer or phone to phone is the modern equivalent of the same type of tyranny that our Founders rebelled against.

I also believe that trolling through millions of phone records hampers the legitimate protection of our security. The government sifts through mountains of data yet still didn’t notice, or did not notice enough, that one of the Boston Marathon bombing suspects was traveling to Chechnya. Perhaps instead of treating every American as a potential terror suspect the government should concentrate on more targeted analysis.

To protect against the invasion of Americans’ privacy, I have introduced the Fourth Amendment Restoration Act. I introduced similar Fourth Amendment protections in December and again just last month. Both measures would have prevented the data-mining we’re now seeing, but both bills were rejected by the Senate. We will see if this time my colleagues will vote to support the Constitution that they all took an oath to uphold.
