[ laughter welcome to "cbs this morning." police in southern california are trying to figure out why a federal agent opened fire on a colleague. the shooting happened at a federal office building in long beach. when it was over, as bill whitaker report, the agent who started it all was dead, another wounded. >> the situation began with what we can characterize as an incident of workplace violence involving two federal agents. >> an office dispute exploded into gunfire thursday at this federal building in long beach, california. authorities say an immigration and customs enforcement agent got into an argument with a fellow agent and pulled out a gun and fired several times. >> another agent working nearby intervened and fired his weapon to prevent additional rounds being fired at the victim. this resulted in the death of the shooter. >> minutes later, police swept in, locking down the area. emergency responders lined the streets as an ambulance rushed the wounded agent to the hospital. >> cbs news has learned the victim was actually the shooter's supervisor. the gunman apparently opened fire after he was told he faced disciplinary action. the fbi is heading up the investigation. late last night about 100 agents were already combing the scene. at times like this, words honestly seem inadequate. as hsi agents, we dedicate our lives to protecting the public and the community from harm. when something like this happens within our office, it's incomprehensible. >> that was bill whitaker reporting from long beach. in the presidential campaign, republican rick santorum is on o the attack. polls show him surging ahead of mitt romney in michigan where romney grew up. >> both candidates campaigned there on thursday taking shots at each other. national correspondent chip reid is watching this new battleground in the race for the gop nomination. chip, good morning. >> good morning, erica and charlie. not long ago, the campaign trail was a very lonely place for rick santorum. now his events are packed and he's become the darling of evangelical christians and tea party supporters. his popularity is due in large part to his deeply conservative views on social issues but now he's going straight at mitt romney on the economy. >> governor romney supported the bailout of wall street and decided not to support the bailout of detroit. >> campaigning in detroit, rick santorum worked to protect his new front-runner status by attacking mitt romney. clearly, feeling the heat, romney hit back. criticizing santorum for decisions he made as a u.s. senator. >> rick santorum voted five times to raise the debt ceiling. he also voted and continues to defend earmarks. during rick santorum's term in office, the government of washington grew by 80%. 80%. >> santorum's numbers have soared in recent weeks and now romney's trailing santorum in michigan, his home turf where he was born and raised and where his father was governor. some political analysts say santorum's surge is not really about him. it's about romney. >> they're looking for somebody, anybody but romney. they've seized on everybody from rick perry to herman cain to newt gingrich and now finally rick santorum. >> many establishment republicans fear that if santorum wins the nomination, past controversial statements on contraception for example, won't play well in the general election. yesterday foster friess who has contributed hundreds of thousands of dollars to the super pac that supports santorum ignited a firestorm of criticism when he used humor in abstinence. >> back in my day, thee used bayer aspirin. the gals put it between their knees and it wasn't that costly. >> excuse me, i'm trying to catch my breath from that. >> liberal women's groups reacted with outrage to that comment, calling it insulting and demanding that both friess and santorum apologize. charlie and erica, the obama campaign has been focused like a laser beam on romney. there are reports this morning that they are turning some of their attention to santorum. >> chip, thanks. former republican senator rick santorum is with us from east lansing, michigan. senator, good morning. >> good morning, charlie. how are you? >> good to see you. your reaction, do you identify with his remarks? do you take distance from his remarks? what is it about them that you disagree with? we're waiting for the connection. can you hear us, senator? we may have lost the connection with rick santorum in east lansing, which is an interesting question here. the kinds of things that senator santorum will have to face is what exactly does he believe about birth control and does he believe it is an important issue in the michigan primary. >> that's come out a lot. one of the things, too, which comes up a lot when we talk about rick santorum, he does appeal, as we know to many conservatives to social conservatives. we hear a lot from him. as he's pulling ahead of mitt romney from the polling, are wanting to hear more from senator santorum about his positions on other issues, like the economy, like foreign policy. >> would it have made -- evident to all of us if michigan has increased importance to the primary and the fortunes of mitt romney and rick santorum. we turn to london where rupert murdoch is in meeting. he and his top aides are trying to clean up after the company had a phone hacking scandal. ten, ten current and former staff members have been arrested since november. murdock is expected to assure employees that he's committed to keeping the newspaper going. the so-called underwear bomber has been sentenced to life in prison. umar farouk abdul-mutallab tried to bring down a jet by setting off a bomb in his underwear. >> at the sentencing, prosecutors showed a video demonstrating the power of petn. that's the explosive material found on abdul-mutallab. as that video played, abdul-mutallab said several times, god is great. his attorney plans to appeal. rick santorum is back in east lansing. i'm sorry about that interruption. let's continue the conversation with the question about foster friess comments. what have you said to him about the comments other than what you have said to the press? >> well, you know, this is someone who is a supporter of mine. i'm not responsible for every comment that a supporter of mine makes. lot of folks, it was a bad joke, it was a stupid joke. not reflected of me or my record on this issue. you know, it's funny that i've been criticized by governor romney and ron paul for voted for something called title 10. federal funding of contraception. this is the same gotcha politics that you get from the media. i'm not going to play that game. i'm not responsible for any comment that anybody who supports me makes and my record stands for itself. i've got a strong record and i'm here in detroit as you mentioned earlier talking about the economy. i gave a speech at the detroit economic club, talked about the energy sector and creating opportunities for everyone in america. that's what our campaign is about. >> there's no question that those issues are important and important to the voters of michigan. also, you have been identified as a social conservative. those issues have been part of what you have said to the country. so this is not gotcha. what this is, is trying to understand exactly what rick santorum stands for and what he might say or do as president. >> charlie, when you quote a supporter of mine who tells a bad off color joke and somehow i'm responsible for that shall that's gotcha. >> nobody said you were responsible. they said how would you characterize it and what have you said to him, not that you were responsible. it's to understand how you differ from what this person said. so let me -- >> now to i have respond to every supporter who says something. i have to respond to it. look, this is what you guys do. you don't do this with president obama. in fact, with president obama, what you did was you went out and defended him against someone who sat in a church for, for 20 years and defended him, that he can't possibly believe what he listened to for 20 years. it's a double standardment i'm going to call you on it. the fact is, i'm here in detroit and we're focused on the economy and jobs. we're going to continue do it. >> i want to get to the jobs and invite you to sit for long conversations with the economy and jobs. and quote you, did you say, one of the things i will talk about, no president has talked about is the dangers of contraception in this country. the whole sexual liberty idea. many in the christian faith have said that's okay. contraception is okay. it's not okay you said because it's a license to do things in the sexual realm counter to how things are supposed to be. they're supposed to be within marriage, for purposes of -- conjugal but also creative. that's what you said. to understand your beliefs. it's an effort to understand your beliefs. >> great. my beliefs are that, as i said, my public policy beliefs are that this contraception should be available. again, i've supported title 10 funding and abstinence-based education because that's a healthier alternative. i am a promoter of that. premarital sext and sex with young girls is a dangerous and at risk bee hafrmt i'm not alone on that. the president even supports policies to try to make sure that folks do not have sex outside of marriage and at risk teens get involved in that at risk behavior that leads to sexually transmitted diseases, unwanted pregnancies, abortions and a laundry list of other things. i do stand behind the idea that abstinence is the best alternative and i've supported that with a program called title 20. >> that's a fair conversation to have. >> yeah. >> let me turn to the politics of michigan. you are now the front-runner many say. what will michigan mean to your campaign and what does it mean to you? >> obviously, i'm very -- i'm delighted that people up here are responding to the message that we're talking about. they're responding to the message i gave at the detroit economic club yesterday. they're looking for someone who understands how to get this economy growing, understands that an important part of that economy is the manufacturing base. it's also energy, it's doing something about the complete explosion of regulation here by the obama administration that's crushing businesses and opportunity. and we delivered that message yesterday. you know, have gotten great response from it. gotten great response across the country shall not just here in the manufacturing epicenter of detroit. but frankly, throughout the midwest. we're doing very well in the states that a lot of blue collar workers who are out of work, looking for opportunities to rise in society, we have an economic plan that reaches down and creates jobs for everybody. >> let me turn to foreign policy if i may. with respect to increased concern about iran, do i understand that you would like to see israel do what now? >> well, my concern about iran is that they cannot get a nuclear weapon. i know that's the president's policy. he's not doing anything to effectuate that policy. in fact, every time we've seen something brought up to try to curb iran and their ability to develop that nuclear weapon, he's opposed it or grudgingly gone along. this would be a game changer for our country, serm for the state of israel. iran -- >> you would like to see israel do what now? what would you like to see israel do now? >> i put forth a 10-point plan including everything from the united states helping the pro democracy movement in iran, trying to do some things to support them. obviously, stepping up sanctions, stepping up covert activity and in fact, putting an ultimatum on the table depending on where our intelligence has devised how close iran is in getting this weapon. if we do believe they're as close as the israelis believe, we have to put an ultimatum on the table, begin to dismantle whatever weapons making capability you're developing or we will put an ultimatum or timeline and take out those facilities. >> senator santorum. thank you. you are one of the few people probably now that have a real chance of being the next president of the united states. so i want to invite to you this program whenever you want to come and have a full conversation about economic and political and social issues that affect the country. so this is an open invitation to you to come back and i hope you'll accept it. >> thanks, charlie. i appreciate it. i look forward to the opportunity again. thanks. >> thanks so much. reports this morning say whitney houston's family will hold a private wake for her later today before her funeral. many big names in intertanment are planning to goodbye in person tomorrow. jeff glor is there in person. >> good morning to you, erica. you remember the mega event that
