pentagon who helped draft the original section 702. he's also an msnbc national security analyst. we also welcome to the broadcast tonight deb reitman, national security reporter for the associated press. so, jeremy, because you were present at the creation of this and one of the drafters, explain what a 702 is and make the case for it. >> it's an authority to conduct surveillance against foreigners outside the united states, take, for example, a terrorist in pakistan whose communications happen to traverse the united states. and when the fbi and the department of justice want to read that person's e-mail or understand what they're plotting against the united states, they can essentially conduct the surveillance without going to the judges of the fisa court each time to get an individualized warrant, which is what you would need to get against an american. so, when the president stood up today and woke up this morning and tweeted, hey, this was an authority used against me to surveil me. no, it wasn't.
