President obama says a terror attack in San Bernardino, california, shows terrorism is in a new phase. In a prime time speech last night, he said america will overcome the threat. The president s address was his first from the oval office in five years. He laid out his plan to defeat isis, also known as isil. He also urged americans to remember the countrys values. We will destroy isil and any other organization that tries to harm us. Our success wont depend on tough talk or abandoning our thats what groups like isil are hoping for. We cannot turn against one another. By letting this fight be defined as a war between america and islam. That, too, is what groups like isil want. Isil does not speak for islam. They are thugs and killers, part of a cult of death. And they account for a tiny fraction of a more than a billion muslims around the world, including millions of patriotic Muslim Americans who reject their hateful ideology. Major garrett is at the white house and new insight on why the president spoke last night. Reporter the views are in and lukewarm to be charitable and the white house was bracing for precisely that. Why did the president give an Oval Office Address that had no news or initiatives or ideas or military strategies against isis . The genesis of the speech started saturday here at the met with his National Security team, it was a consensus that this administration was losing control, losing grip on the entire National Conversation about isis and the president needed to get involved in that conversation to try to accomplish three things. First, to convey to the nation that the campaign against isis is more muscular and more aggressive. There are more u. S. Bombing runs and the british are now bombing in syria, there are troop commitments from germany and there is much greater intelligence sharing with the french. The president also wanted to address the gun control argument. Even though the Political Climate on capitol hill was republicans in control of the house and Senate Remains hostile. The president believes the fact pattern in San Bernardino strengthens not weakens his gun control argument and wanted to make that case. Thirdly, most importantly, when you talk to people at the white house, the president believes the country could turn on itself and this message of tolerance for Muslim Americans is not just about that. Pure tolerance. But it is a counterterrorism strategy. Maintain good solid working relationships with the Muslim Community in this country, not just as an matter of tolerance, but as a matter of counterterrorism success, being able to detect and fill at any rate and potentially stop terrorist attacks before they start. There was a good deal of conversation about whether this president should give this address. Today or possibly tonight. But the president wanted the largest prime time audience he could find, sunday was it. He knows the reviews are tepid but this president has long relied on speeches and ignored shortterm analysis to play what we always talk about here at the white house as president obamas long game, whether its rhetoric or strategy to defeat isis. Major, thank you very much. Investigators have new information this morning on the suspects in the San Bernardino case. Syed Rizwan Farook and his wife Tashfeen Malik killed 14 people and wounded 21 others. Officials say they got their carter evans is outside of emerging about the couples apparent radicalization.

Syed was a talker. A lot of people think he was very quiet. I didnt get that impression of him. Because we have heard he was very quiet. Huhuh. Reporter really . Very confident when he talked. There was times when we walked out of work in the morning and i couldnt get him to stop talking. Reporter Chaz Harrison met syed Rizwan Farook in college in 2008 and they later worked together and he said he watched him change over time. He liked to talk about cars a lot, taking things and building things, hed like to talk about religion. A lot. He wanted to start a business. He wanted to just get a truck with some tools in there and go around and fix peoples cars. So there was a point where he was definitely making longterm goals. Reporter here in the United States . Yeah. Reporter how religious was he . Very. Shot . Yeah. And that is what is puzzling, why . I always try to call him, as i called every Single Person that possibly could have been in that building to find out they were okay and im over here calling this guy to find out if he is okay and he is the shooter, you know . How do you reporter you felt it was on the fbi . I let the fbi know that he didnt want to be in the United States, but he told me him paying taxes was helping the United States support basically the war on islam, the war on muslims. Reporter what did you know about his wife . He was very secretive about his wife. He didnt want to reveal much about his wife. One of the first things i said, hey, you got a picture . He said she was very uncomfortable. Everyone look at her instead of the way she dressed. Reporter harrison says farook told him he wanted to leave america because he didnt think he could practice his religion the way he wanted here.

There will be a necessity to significantly increase the number of u. S. Special operators. Reporter on face the his support for tracking muslims in the u. S. I think there could be profiling. Reporter and called for tougher treatment of the families of suspected terrorists. I would certainly go after the wives who absolutely knew what was happening. And i guess your definition of what i do, im going to leave that to your imagination. Reporter some gop rivals, chris christie, said the recent attack highlighted the need to grant Greater Authority to u. S. Intelligence agencies. If you give these people the tools, they will act constitutionally and they will prevent many, more attacks than will get through. Reporter rand paul, who has clashed with christie over the issue of surveillance, said the answer was restricting immigration. We have to be careful who comes here from the middle east. Reporter Hillary Clinton distanced herself from the president s counter isis strategy. We are not wing but too soon to say we are doing everything we need to do.
