the ability to strip p.i.i. for information that leads to the n.s.a. don't you do that today? >> i would think we could do that in an automated fashion. one of the reasons why i would want to have a discussion about exactly what kind of information we're talking about and i can build until the protections in terms of the messenger cal even if a company doesn't have the capability today but say, hey, i want this. it it's going to give it to you. you have the ability to strip out i think we could that. in past conversations that's -- at least what the nebraska told us. myory e only fear is -- and again this is the billingest debate. you want exens for volunteer and the standards are right if they are in fact, in good faith trying to provide a source code ithout p.i.i. when

accidentally and it could happen that p.i. gets through. you'd want the n.s.a. to have a system to strip that data bates which is easier for you tow do. i would argue. then the thousands of companies trying to share malicious source code that may have riginated in russia, or some crime element e element. i just want to make sure we have an open discussion about what that looks like and why there aren't concerns about limiting the number of partis paints. it adds more vulltiality for the whole system. you are save by the bell. the vote, the close shows zero. i want to thank you for your country. the i hope you'll take back as a

committee that in a bipartisan does pretty good. i think you've seen that. >> yes, sir. >> we have the it motte respect for the work that they're doing. thanks for their pitritism despite what they might read in -- their patriotism despite what they might have read in the paper. thank you so mufment -- much. >> up next on c-span, a discussion on negotiations concerning iran's nuclear program. then a forum on the terror group known as isis and why some werners are joining it. q&a, david r on

mark. >> all the week on c-span we'll have interviews with retiring members of congress. tonight, we will talk to tom petri and caroline mccarthy. e was first elected in 1978. congresswoman mccarthy has served 10 years of her own. saying current leaders need to know when it's time to move on. ere's part of her remarks. >> we have a lot of talented younger members. pelosi just by the way did. she's really good at raising money. i was never good at that. they have to start training younger people and bringing

younger people into the caucus to become hopefully the future leaders. one of the things they dernsi believe with all my heart and soul, you to know when to leave. nancy doesn't feel that this is the time to leave. many thought she might stay for this common year. but when i look around is anybody really ready to relace that. and i give hear lot of credit for what she's been able to do. but i think it's fine that the leaders, you know, stop looking at who's going to fill my spot. we're all replaceable. there might be some bumps on the road but i do always believe that young every people can take our spot with fresh ideas and new ways of doing

things. i see nothing wrong with that. that's a normal progression. >> c-span interviews with retiring congressional members and nsin tom petry caroline mccarthy. >> here are a few of the comments we recently received if our viewers. >> i just have to tell you that these people in person, to hear them have the panel discussion on on congressional hearing. it is so important to -- i'm context and the to listen to it in its entirety. i really like, you know,

- pick the time to not only -- just what they right. . they stimulate the conversation. yes,. took two lunches. i watch c-span all the time when i'm home. it's the only station i have on most of the time. i think it's absolutely excellent. i watched all of the debate around the country. thank you for this book talks and for the history. i like all of it. and i'm. thank you very much. >> and continue to let us now what you think about the programs you're watching. call us at 220-626-3400. you can send us a tweet at
