BOB SCHIEFFER: Today on FACE THE NATION, politics, poverty, and ladies of the night.
PRESIDENT BARACK OBAMA: If it turns out that some of the allegations that have been made in the press a-- are confirmed, then, of course, I'll be angry.
BOB SCHIEFFER: If that is so, he must be furious because the scandal over sex and the Secret Service has caused people who seldom agree on anything to unite in outrage.
SARAH PALIN: Well, check this out, bodyguard, you're fired. I've had enough of these men being dogs and not being responsible.
BOB SCHIEFFER: But if all the questions have been answered, has the Secret Service been damaged beyond repair? We'll ask former Secret Service director Ralph Basham, and we'll bring in four key legislators investigating the case--Senators Joe Lieberman and Tom Coburn, and Representative Sheila Jackson Lee and Elijah Cummings.
Then we'll do a campaign quick check on the presidential race where Mitt Romney had this to say to the President.
MITT ROMNEY: Start packing. That's what I'd like to-- like to say.
BOB SCHIEFFER: Polls show Romney is closing in on the President, but is it a little early to be measuring drapes for the Oval office? We'll ask his longtime advisor Eric Fehrnstrom and Stephanie Cutter, the President's deputy campaign manager.
We'll talk about the changing face of poverty with the authors of a new book, Tavis Smiley and Cornel West.
And we'll get analysis on all of it from the Washington Post's Melinda Henneberger; National Journal's Major Garrett; and our own political team, John Dickerson and Norah O'Donnell.
That's a lot to cover but this is FACE THE NATION.
ANNOUNCER: From CBS News in Washington FACE THE NATION with Bob Schieffer.
BOB SCHIEFFER: And good morning, again, and welcome to FACE THE NATION. Senator Joe Lieberman who is chairman of the Senate Homeland Security & Government Affairs Committee is with us here. They do have congressional oversight on the Secret Service.
So, Senator, let me just get right at it here. On Friday another three Secret Service agents resigned, and the Secret Service announced that another agent was under investigation in a separate incident. Do you know what this-- this latest person to be identified--
SENATOR JOSEPH LIEBERMAN (Homeland Security & Government Affairs Committee Chairman/I-Connecticut) (voice overlapping): Yeah.
BOB SCHIEFFER: --that what that had-- what-- what's going on there?
SENATOR JOSEPH LIEBERMAN: Right, Bob. The-- those announcements on Friday were significant in two regards. One is that it shows that Director Sullivan at the Secret Service is pursuing this investigation aggressively and comprehensively. It's clear to me now that he's interviewing everybody from the Secret Service who was in Cartagena. But what-- what is-- what was striking to me and significant is that the twelfth Agent now put on administrative leave as of Friday was not staying at the Caribe Hotel where the other agents were, but at the Hilton. And the Hilton is significant because that's where President Obama was going to stay. Now we don't know at this point what that twelfth agent is-- is being charged with and why he's been put on administrative leave. But now you're into the hotel where the President of the United States was going to stay. And it-- it just gets more troubling.
BOB SCHIEFFER: Do you have any indication yet of whether any White House staffers who were involved because any time the President travels overseas, as well as the Secret Service and the security people who go in advance, there are always White House staffers who go as part of the advance team. Do you have any indication anybody from the White House was involved?
SENATOR JOSEPH LIEBERMAN: I-- I don't, Bob, but I-- I'll tell you if-- if anybody at the White House asks for my counsel on this, I would say they ought to be launching their own internal review of all White House personnel, advance teams and the rest, who were in Cartagena to make sure that no one working for the White House was involved in any of the same kind of inappropriate behavior that the Secret Service agents were. Obviously, a Secret Service agent has a different range of responsibility than somebody on a White House advance team. On the other hand, if we're worried about compromising through sexual favors, the security of the President of the United States, the White House advance team, obviously, knows exactly where the President's going to be at every moment. And they have a responsibility in my opinion to conduct themselves at all times when they're working for the President in a way that doesn't make them vulnerable to being compromised by anybody who wants to do the President harm.
BOB SCHIEFFER: Where-- where is your committee on this? Are you going to hold hearings? Are you actively investigating? Where are you?
