The Federal Reserve raised a key Interest Rate for the first time in years. Wall street took that as a vote of confidence in the economy and the dow rose 224 points. Reporter the aftershocks from the financial crisis and the housing meltdown forced the fed to keep Interest Rates near zero for more than seven years, but today, janet yellen declared an end to the extraordinary era of easy money. The economic recovery has clearly come a long way, although it is not yet complete. Reporter it was back in december of 2008 that the fed slashed rates as low as they could go, the same month the economy was ofofcially declared in recession and Bernie Madoff was arrested in a billiondollar ponzi scheme. By april of 2009, foreclosures had soared to their peak, more than 200,000 t tt month. And by october, unemployment was at 10 . But now monthly foreclosures are down 80 from that high, and seven years later, unemployment has been cut in half. So the fed is raising rates a quarter of a point. And it reflects the committees confidence that the strengthen. Reportete future increases will be gradual, and the central bank made certain the markets saw this coming. This is the most telegraphed punch in the history of the world. Reporter max wf is chief economist t manhattan venture partners. That being said, though, its still symbolic. Its still closed, the bookend of a period. This is the most stimulation Monetary Policy has ever given to o o economy, and hopefully well never need this much again. Reporter several major banks raised their prime rates immediately after the feds move, and the cost of mortgages, car loans and credit cards could begin to rise. But its good news for savers who will finally start to get higher returns on the money theyve socked away. Scott. A long hangover from the great recession. Anthony, thanks very much. Public schools in los angeles reopened today. They closed yesterday, abruptly, because of an email Terror Threat that turned out to be a hoax. 640,000 students were shut out. Threat, but dismissed it. Today, the federal government revised its system for wning americans of terrorist threats. The department of Homeland Security issued its first bulletin today. It was a statement of what is already painfully clear. Jeff pegues has more on this. Reporter todays bulletin says the country is in a new phase in the global threat environment. Law enforcement is concerned about selfradicalized individuals who could strike with little or no notice. It also warned of threats against communities based on perceived religion, ethnicity, or nationality. The new bulletin alert was added because the other two categoriri, elevated and imminentntrequired detailed information and were never activated. Bulletins like todays can be sent without a specific threat. Homeland security secretary jeh johnson. What we are concerned about, copycatlike attacks, and those who are selfradicalized who may be inspired to commit terrorist attacks. And regrettably, w whave seen that in recent months and recent recent weeks. Reporter the massacre in San Bernardino, california, two weeks ago was one such attack. So were the july 16 shootings that killed five people at two military locations in chattanooga, tennessee. Today, for the first time, fbi director james comey, said the shooter, Muhammad Youssef abdulazeez, was also selfradicalized. Theres no doubt that the chattanooga killer was inspired, motivated by Foreign Terrorist Organization propaganda. Weve investigated from thth beginning as a terrorist case. Reporter comey said before San Bernardino shooter Tashfeen Malik came to the u. S. , she only communicated about jihad using direct private messages and not publicly on social media. Scott, that would have made it harder for immigration officials to see signs of her radicalization. Now, because the fbi has determined that that chattanooga shooting jeff just mentioned was terrorism, the navy said today that four marines and a sailor who were killed and a marine who was wounded will all receive purple hearts.

Homeland security was the focus last night at the republican president ial debate las vegas. 18 Million People watched it on tv, and Major Garrett was there. Marco knows what hes saying isnt true. Reporter firstterm senators marco rubio and ted cruz sparred over Congress Decision toned the governments bulk collection and storage of phone records. Rubio opposed ending the program, and cruz supported it. That tool we lostthe uetadata program, was a valuable tool that we no longer have at our disposal. The old program covered 20 to 30 of phone numbers to search for terrorists. The new Program Covers nearly 100 . Thatives us greater ability to stop acts of terrorism and he knows that thats the case. I dont think National Television in front of 15 Million People is the place to discuss classified information. Rising tensions between the two as they vie to challenge gop frontrunner donald trump. Today, cruz rebutted rubios implication that he revealed classified information. What i said last night has be widely reported. Its been saturated in the public sphere. Thisiss another example of the Rubio Campaign trying to spread misinformation. One of the most important things a president has to do is be able to handle both the role as the bully pulpit of the white house, but do so in a way that doesnt compromise our national security. Reporter after the debate, we asked trump how he would balance privacy and security. I have always come down on the side of security. To me its the most important. Reporter even if it means doing something to encroach on the bill of rights . I hate it, i hate the concept of i but were dealing with some very, very bad dudes. Reporter jeb bush h id trumps Foreign Policy proposals were not serious. Hes a chaos candidate. And hed be a chaos president. He wld not be the commander in chief we need to keep our country safe.

The americans are supporting allied militias, including kurdish forces, that our Charlie Dagata linked up with near the isis capital city. Repororr the thick fog meant the drive to the front line inside syria was slow. We were about 40 miles from raqqah, the headquarte of isis, but their fighters were just a few miles away and no onene wanted to make a wrong turn. Past deserted villages, we finally reached their line of defense. It wasnt mumu. One of the soldiers looked like these are the Syrian Rebels the u. S. Is training and equipping. Until a few months ago, thisis whole area was controlled by isis. Gloomy days like these are a nightmare for rebel forces guarding the front lines. Isis militants use the fog as cover to launch sneak attacks. They cant see them coming until its too late to stop them. The group leader told us u. S. Warplanes cant see them, either. And while he said he was grateful for american support, he hadnt actually seen any of the u. S. Special forces now on the ground. But commmmder Lewland Rojava had. We met h h at his base camp deep inside syria. What types of things are you discussing . Mainly coordination on the ground, he told us, weapons and ammunition and who gets them, and they also wanted to see how successful we are in fighting isis on the ground. We also asked villagers what inside syria. If they bring peace and stability he said, theyre welcome. When you found out u. S. Troops were coming re, what did you think . 16yearold omar told us he was simply h hpy. The commander told us, scott, once u. S. Forces see for themselves what theyre up against, theyll realize they need things like Armored Vehicles and heavy weapons, in addition to guns and ammunition. He also said, depending on how things go, maybe america will Charlie Dagata with a report from americas new battlefield in syria. Charlie, thank you. Now the u. S.

Balaclavas provide scant relief against the choking dust. Theyre searching for boko haram, the Extremist Group that has aligned itself with isis and killed more than 20,000 in the past six years. Border towns like kolofata have suffered a string of attacks by suicide bombers recently. Boko haram fighters frequently hide weapons and ammunitions in villages. Sniffer dogs look for explosives as soldiers go from hut to hut. The belief is boko haram could be in any of these homes and not even children are imne from secucuty checks because in the past few months, the suicide bombs in this area have all been delivered by children. The new face of war. But today, they find nothing. Major r ltus kwene tells thehe village to be vigilant. Miles from the border. And youve been attacked here at this base. We underwent a massive attack at this base. Reporter kwene told us since boko haram has pledged allegiance to isis, their tactics have changed. Their bombs are more sophisticated and deployed with deadly frequency. When i see how horrible they can be, i think i will never, ever feel tired to fight against them.
