(CNN) -- Here are some of the most quotable sound bites from the Sunday morning shows:
On airport pat-downs:
"The challenge is, how do we balance the security that everybody wants -- everybody wants to make sure they get to their destination safely -- with the privacy that everybody wants also. How do we find that precise blend for each person?" -- TSA Chief John Pistole, CNN's "State of the Union"
"Clearly, if we are to detect terrorists, who have again proven innovative and creative in their design and implementation of bombs that are going to blow up airplanes and kill people, then we have to do something that prevents that." -- Pistole, "State of the Union"
"I am absolutely confident that our security experts are going to keep trying to get it better and less intrusive and more precise. But at the same time, we want people to travel safely." -- Secretary of State Hillary Clinton, NBC's "Meet the Press"
"I'm very attuned, given all the concerns that have been raised, to answer this question directly. No, we're not changing the policies, because of that, because of the risks that are -- have been identified because of the current threat in the stream." -- Pistole, "State of the Union"
On the movement to opt out of body screenings Wednesday and instead receive a pat-down:
"I think the public needs to work with us and we'll get it right. I'm not going to support that. But ... we need to get it right, and we will." -- Republican Rep. John Mica, "State of the Union"
On whether they'd submit to a pat-down:
"Not if I could avoid it. No. I mean, who would?" -- Clinton, CBS' "Face the Nation"
"I don't think any of us would want to undergo that. I don't think any of us feel that the discomfort and the delay is something that we like. But most people understand that we've got to keep airplanes safe." -- Democratic Rep. Steny Hoyer, "Face the Nation"
On NATO's plans to turn over all security in Afghanistan to the Afghan government by 2014:
"We think that's a reasonable goal. Obviously, there's a lot between now and then. NATO also affirmed that that transition would start in the spring. We don't know exactly where it will start, but I'm confident of that date." -- Adm. Mike Mullen, chairman of the Joint Chiefs of Staff, "State of the Union"
On whether the Senate should take up the START treaty this year:
"I wouldn't describe it in any other way than I have in terms of there's a sense of urgency that I think -- and there's an opportunity to get this done now. And from a national security perspective, I really believe we need to do that." -- Mullen, "State of the Union"
"I have a great deal of respect for all of my colleagues, Democratic and Republican, in the Senate. And I think that everyone is trying to figure out how to do the right thing on this important treaty." -- Clinton, "Fox News Sunday"
"We are making the case that, number one, this is in America's national security interests. Our friends and allies around the world support this. We need to get inspectors back on the ground. Remember what Ronald Reagan said when he was passing an arms control treaty with Russia, "Trust, but verify." Right now, we cannot verify. And this is the kind of important national security agreement that the Senate needs to be encouraged to stop and really study and focus on." -- Clinton, "Face the Nation"
On North Korea:
"I've been concerned for a long time about instability in that region and, quite frankly, North Korea has been at the center of that. We've worked hard with other countries to try to bring pressure on them to have them comply. They haven't done that." -- Mullen, "State of the Union"
On why he supports repealing "don't ask, don't tell":
"Because I think it -- it belies us as an institution. We value integrity as an institution." -- Mullen, ABC's "This Week"
On political aspirations:
"I am very happy doing what I'm doing, and I am not in any way interested in or pursuing anything in elective office." -- Clinton, "Fox News Sunday"
"I don't want to be the president of the United States. I do want to work with these governors across the country to make the states more pivotal, more powerful, as they should be." -- Republican Gov. Rick Perry of Texas, "Fox News Sunday"
"My only political aspiration is to be re-elected governor for a second term." -- Republican Gov. Bobby Jindal of Louisiana, "Meet the Press"
On Nancy Pelosi as House minority leader:
"Well, had she not run, I would have run for leader. And I think I would have been elected leader. Having said that, this election was, I think, about issues, about concerns and anxieties that the American people have, not about personalities. They want us to focus on jobs and growing the economy and bringing the deficit down. I think Leader Pelosi will do that. I'll do that. Hopefully, our Republican colleagues will do that as well and we'll find common cause to reach that objective." -- Hoyer, "Face the Nation"
On whether President Obama is a one-term president:
"I think it's up to him. ... If he changes directions, he can certainly make a stronger case. But if he stays, if he doubles down on his current path, I think it would be very hard to make the case two years from now that he deserves to be re-elected." -- Jindal, "Meet the Press"
