Former FBI counterterrorism agent implies that US records all US phone calls

Glenn Greenwald notes the alarming revelation from a CNN Out Front interview between host Erin Burnett and Tim Clemente, "a former FBI counterterrorism agent," where Clemente claimed that the FBI had access to recordings of every phone call made in America:

BURNETT: Tim, is there any way, obviously, there is a voice mail they can try to get the phone companies to give that up at this point. It's not a voice mail. It's just a conversation. There's no way they actually can find out what happened, right, unless she tells them?

CLEMENTE: "No, there is a way. We certainly have ways in national security investigations to find out exactly what was said in that conversation. It's not necessarily something that the FBI is going to want to present in court, but it may help lead the investigation and/or lead to questioning of her. We certainly can find that out.

BURNETT: "So they can actually get that? People are saying, look, that is incredible.

CLEMENTE: "No, welcome to America. All of that stuff is being captured as we speak whether we know it or like it or not."

Are all telephone calls recorded and accessible to the US government? (via /.)
