President obama addresses the nation tonight on how his administration intends to keep the country safe in the wake of the San Bernardino attack. The fbi is now investigating the massacre as the deadliest act of terror on american soil since 9 11. Well speak with the chair of the House Homeland SecurityCommittee Michael Mccaul in a moment. But first we have fox team coverage. Will carr at one of the crime scenes in california. And kevin cork at the white house. Kevin . Reporter good day to you. For the first time in over five days the nation will address the president from the oval office. And address we are told that could last about 20 minutes. And we are told by the officials that the American Peoples safety and security remain his top priority. We expect the president to highlight increasing security abroad and hell call for sensible gun reform legislation. And we got a bit of a tip of the hand on that in listening to his weekly address. Right now people on the nofly list can walk into a store and buy a gun. Thats insane. If youre too dangerous to board a plane, youre too dangerous by definition to buy a gun. No surprise the New York Times walking in step with the white house on this writing in an editorial, its not necessary to debate the peculiar wording of the Second Amendment. No right is unlimited and immune from reasonable regulation. Meanwhile, the president S National Security team convened in the situation room yesterday breaking down, of course, the very latest intelligence on the attack. Though the white house in a statement said that they, quote, as of yet uncovered no indication the killers were part of an organized group or formed part of a broader terrorist cell. Although isis is claiming that the two is operating in support of their group. What is less clear, however, is why it took the white house so much longer for the fbi to determine that this was, in fact, a terrorist act. We could learn a lot more about that tonight. Chris . Kevin cork reporting from the white house. Thank you for that. Now lets bring in will carr in redlands, california, the scene of the investigation. Will . Reporter chris, authorities are trying to figure out how the two suspects terrorists flew under the radar into a Southern California neighborhood. On saturday they raided a home in california. We are told enrique marquette may have legally purchased semiautomatic weapons used in wednesdays shooting. Marquette has not been checked and he checked himself into a Mental Health facility. Now the focus of a terrorism investigation has checked into the 29yearold mother who collected cash, ammunition and ieds inside their apartment in redland. Neighbors noticed suspicious activity in the couples garage for a couple weeks but did not call the authorities because they did not want to racially profile. We are learning she may have been the one who radicalized faruque and she may have been the bombmaker. I think the female assailant at this point may have been angry to marry someone with a clean record so she could bring terrorism to the United States. Reporter malik was born in pakistan and spent time if saudi arab arabia. She was granted her conditional green card this past july. The Investigation Continues and the community is remembering the 14 lives lost. Well be listening intently to the president s address. Chris . Will carr reporting from redlands, california, thank you. Joining us now, congressman michael mccaul, chair of the House Homeland Security committee. Congressman, what have you thought of president obamas response so far to the San Bernardino attack and what would you like to hear him say in a speech to the nation tonight . Reporter well, first, he seemed to indicate going back to the fact that this could be an act of Workplace Violence. He has to get off this rhetoric. Make no mistake, this is not Workplace Violence. It was an act of terrorism and these occurrences are happening too frequently. I think the tentacles of isis are not just in europe but also in the United States of america. And the fbi stats show that. We have 70 isisrelated arrests, more than one per week. A thousand investigations in all 50 states. I wanted to tell the truth to the American People about what the threat really is and what the threat itself is, and thats radical islamist terrorism. It does exist in the United States. We didnt see this one coming. There were no warning signs or flags. And we need to do a better job identifying the signs of radicalization from within the United States. We also need to stop the foreign fighter from traveling overseas into the United States. Those are the two main threat vectors. And chris, were just not doing an adequate job to adequately protect the American People. Lets turn to the investigation. This is what we heard on friday from fbi director james comey. The investigation so far has developed indications of radicalization by the killers and of a potential inspiration by foreign terrorist organization. Chairman, is there anything more you can tell us about this couple and about their links to terrorists either in this country or overseas . Well, i think, yeah, the wild card here is the wife malik. They are both of pakistani decent, but she lived in pakistan most of her adult life, went to saudi arabia, they hooked up over the internet. Theres a Serious Investigation ongoing into what she was doing in pakistan and saudi, including if she attended the red mosque, which is a radicalized mosque. We think that she had a lot to do with the radicalization process. And perhaps with mr. Faruques radicalization in the United States. Im sorry, sir, let me can if i can go down a checklist that a lot of people are asking, your sense at this point, were they inspired or directed by isis or some other group to carry out these attacks . Well, at a minimum, inspired. We know malik, the female pledged her allegiance to al baghdadi, and isis in a computer, we have their devices, we are going through the forensics. They tried to destroy those computers unsuccessfully. And now the investigation is ongoing to find out what is precisely the connection between isis and raqqah and the United States and what was going on. I believe at a minimum inspired but could be directed by the Internet Communications which is this, come to syria or kill where you are. When you talk about the connections, one of the questions a lot of people are asking is where did they get the thousands of dollars that must have taken to assemble this huge arsenal of weapons and ammunition and material for bombs. Youre right. We are looking at the forensics in this case. I believe on his salary he could not buy this on his own. We know one of the suspects was provides the semiautomatic weapons to him as well. So thats all part of the bigger investigation in terms of who was providing, not only the finance but also the expertise. Its been reported they had a bombmaking factory, if you will, inside their home. They had already built 12 pipe bombs ready to use. And who knows what the next target could have been. As the house of homeland security, one of the questions you have to be asking is why didnt we find this out . Were talking about an american citizen. It seems to have come under the radar. As you look at this, several days into this incident, any sign of an intelligence failure, an intelligence gap that was exploited . Or is this just something that we couldnt find . Thats something well be looking at on the committee, the oversight, to see what could have been missed. Could we have done a better National Security check over in saudi arabia on the female suspect to find out what her background really was before we let her in on a fiancee visa . These are a lot of things in congress i came up with to strengthen foreign travel. But to deal with combatting islamic extremism in the United States, we have a little priority or focus on these programs. And i think we need to do a much better job trying to identify the Early Warning signs of radicalization inside the United States. But i guess at some point you just cant do it, and thats the question im asking as someone who is charged with protecting the homeland, is it possible to stop, hes an american citizen, he had no Law Enforcement record, no evident ties to terror, yes, there was the wife and thats certainly a question, is it possible that sometimes you just cant spot these terrorists before they strike . Thats right. You just cant stop it all. And we stopped a fourth of july plot and we stopped a lot of bad things from happening, chris, but you just cant stop it all when you have 2,000 isis tweets per day on the internet coming into the United States to kill. There were no flags, warning signs in this particular case, but the volume is so high and the chatter is so high that its almost impossible to stop it all. And i think that is what we are ramping up our efforts but you cant be right every time. Lets go through in the time we have left of a list of possible reforms, i want to get from you whether you think they are good ideas or not. As you pointed out earlier, the wife, malik, came in through a socalled fiance visa. Do we need to end those . Well, i think more scrutiny needs to be placed on the National Security investigation to get that visa. As you know on the floor on tuesday, well be voting to a Visa Waiver Program bill to tight up up the restrictions so that people who have basically have those visa waiver countries, for instance, the french attackers have a french passport wouldnt have to get a visa to come into the United States. Thats vitally important. And the majority of the attackers let me ask you about that because i think a lot of you may not know, well talk about the fiance visa. In 38 countries, in europe, theres a visa waiver. They can come into this country, a lot of them come, hundreds of thousands of them come without any screening at all. Does that have to stop . Well, it does. And thats what our bill fixes on tuesday. 5,000 of these foreign fighters that have gone to syria and iraq have western passports. And therefore do not have to obtain a visa before they come into the United States. Now chris, this is a huge security gap. It needs to be addressed and fixed and the congress understands that as does the white house, and we intend to do that. But if you think again about the majority of the paris attackers have french passports, they wouldnt have had to go get a visa before coming to the United States. Thats a threat to the homeland, its a threat to europe, obviously, but the bigger threat to the homeland is the ease of travel visa waiver to get into the United States. Another area you were one of the majority in congress who voted to end the nsas bulk collection of phone data, the fact that my phone number called your phone number and spoke for x number of minutes. And that program ran out last sunday, a week ago. As a result of that, that means that authorities are going to have access to only the last two years of farooks phone records, but now the previous three years because they have five years in their file, the previous three years, those years in their files are now off limits. Was it a mistake to end the nsa phone Data Collection program . Basically what we did is we took i was a former federal prosecutor, i did warrants, and what we did is would go to the phone companies to get that information. Rather than have all the information warehoused under the federal government. And so i think its coming back to a system that worked in the past. Its just going to the private sector to get that information and not taking all that data and warehousing it under the nsa. Im sure there will be debates in the congress further about this. I feel confident about our ability to track terrorists through court orders and getting into these phone records. What im more worried about, chris, is this dark space phenomenon of communications between terrorists from raqqah into the United States, or raqqah to paris or belgium. Even with a court order, we cant see the encrypted communications they are using. And if you cant see what the terrorists are saying, you cant stop it. And thats one of the Biggest Challenges before the fbi today. Finally, chairman mccaul, i want to end where i began because one of the things that struck me in your initial answer about what you want to hear from the president tonight is you said you want him to tell the truth. You dont think hes been telling the truth to the American People . Well, you know, before paris he said, isis was contained. Before San Bernardino, he said that america was safe from isis, was not an extend shl threat. He seems to downplay this throughout his Campaign Narrative into his presidency and i think the American People deserve to know what the truth really is. And we also want to hear from him a military strategy to finally defeat and destroy isis, drain the swamp to the swamps in syria so they cant come into the United States. And San Bernardino is an example of the swamp coming to the United States. Chairman mccaul, well have to leave it there. Thank you so much for your time today. Thanks, chris, thank you for having me. Up next, well bring in our sunday group to discuss the San Bernardino attack and how president obama will try to reassure the nation. Plus, what would you like to ask the panel about what we can do to protect the homeland . Go to facebook or twitter at Fox News Sunday and we may use your question on the air. The markets change, at t. Rowe price, our disciplined investment approach remains. We ask questions here. Look for risks there. And search for opportunity everywhere. Global markets may be uncertain. But you can feel confident in our investment experience. Around the world. Call a t. Rowe price investment specialist, or your advisor. And see how we can help you find global opportunity. T. Rowe price. Invest with confidence. We have a pattern now of Mass Shootings in this country that has no parallel anywhere else in the world. It is possible that this was terrorist related. But we dont know. It is entirely possible that these two attackers were radicalized to commit this act of terror. President obamas evolving reaction this week to the San Bernardino massacre. Tonight hell address the nation about how he intends to confront the Terror Threat. And its time now for our sunday group, fox news senior political analyst brit hume, julie pace who covers the white house for the associated press, syndicated columnist george will and political analyst juan williams. Julie, as soon as you heard the president was going to be speaking tonight im sure you were busy working your sources at the white house. What do you expect him to say tonight and is there a chance hell announce the dramatic escalation on terror . To your last question, no, no major policy announcement. Nothing in terms of Troop Deployment or major shift in strategy for going after the Islamic State abroad or trying to track people radicalized in the u. S. I think that more broadly this is an attempt by the president to acknowledge that for a lot of americans after the attacks in paris and now in california that the Terror Threat feels much more real, much more closer to home than it has previously. So i think some of this is going to be him talking about it in a way that i think a lot of people hoped he would have talked about it previously. And also to show that he does take this seriously. The optics of this are important. The president hasnt delivered an Oval Office Address to the nation since 2010. He has often ashoed the optics of the job and this is a way for him to show people visually he understands that this is something that people are taking very seriously. To the degree that he was behind the curve of a lot of americans this week where he was talking about
