Captioning funded by cbs ted by toyota. Lets go places. Captioning funded by cbs welcome to cbs this morning. Good morning, norah. Good morning, charlie. We begin in iraq. The newest challenge to iraqs embattled government comes from washington. The Obama Administration and key lawmakers are suggesting this morning that iraqs Prime Minister should resign. Meanwhile, sunni muslim militants are advancing into new territory. Iraqs Largest Oil Refinery is at the center of the battle. Holly williams is in erbil tracking the sunni uprising. Holly, good morning. Reporter good morning. Iraqi officials are denying reports that they have lost control of the countrys Biggest Oil Refinery and instead claim that they killed 70 militants there, losing control of that complex would be yet another blow for iraqs besieged government, which depends on oil revenues. Internet videos show smoke billowing where the militants claim they have taken control of the oil refinery. And in this video, also posted online, theyre seen parading triumphantly through the town. Other sources say the battle for the baiji refinery is still raging. 60 miles north outside the city of kirkuk kurdish fighters are also taking on the militants. But as in baiji, theres Something Else at stake here. Kirkuk is rich in oil and a prize for whoever captures it. When the militants first swept through this region last week, iraqi soldiers abandoned their posts, leaving Northern Iraq to descend into chaos. The kurdish fighters are well disciplined. Wheres isis . How much further down the road . Reporter but their goal is to protect their own region in the northeast and win control of oil supplies, not to push the militants out of iraq for good. Just outside of kirkuk, and this is the last safe checkpoint along in road the men here are telling us that the militants are just over there in the mountains. But they were content to hold them back rather than confront them. With different groups in iraq fighting for their own interests, kurdish leader jauad mohammed told us allout civil war may be unavoidable without u. S. Intervention. We need u. S. Air strikes before the militants make it to baghdad, he said. They cannot let them reach baghdad. Many other iraqis oppose u. S. Air strikes but nearly everyone weve spoken to here fears that their country is rushing towards a bloody civil war. Charlie. Holly, thanks. American aircraft are flying around the clock Surveillance Missions this morning over iraq and the Obama Administration is considering iraqs request for air strikes against the sunni militants. Bill plante is at the white house where the president conferred with leaders from both parties. Bill, good morning. Reporter good morning, and good morning to our viewers in the west. This all comes as the u. S. Is urging the iraqis to form a more inclusive government, and u. S. Officials are saying that they will make clear what attributes iraqs leaders need. Now that is code for saying that the u. S. Believes iraq would be better off without its current Prime Minister neuroal maliki. The president talked to the leadership yesterday. After the meeting, the white house said that the president reviewed options for increased Security Assistance something joint chiefs chairman Martin Dempsey told congress the iraqis have been pushing for. We have a request from the Iraqi Government for air power. We do . We do. Reporter at the white house, outgoing press secretary jay carney repeated the Administration Position that a political reconciliation is whats needed. There is no military solution that will sustainably solve iraqs problems. Any consideration of military action must be informed by the situation on the ground and the objectives to be obtained as well as the consequences of its use. Reporter prior to the meeting, House Speaker john boehner said that he was looking to the white house for a plan to keep the gains secured by years of u. S. Military involvement in the region. The president needs to outline an overall strategy for success, and im hopeful that today in our meeting ill hear from him. Reporter the leaders departed without talking to reporters, but in a statement, Senate Minority leader Mitch Mcconnell blamed the weakness of Iraqi Security forces on the president s withdrawal of u. S. Troops without what he called a u. S. Presence capable of preserving our gains and mentoring our partners. In a morning speech on the senate floor, majority leader harry reid spoke out against said mcconnell and his supporters were distorting history. Would they have preferred that our soldiers stayed in iraq . In harms way . What has been taking place in iraq . Its a civil war. Reporter senator reid declined to share any of the specific details of the meeting afterward, but Senate Majority leader Mitch Mcconnell did tell reporters off camera that the president indicated to them he did not expect to need Congressional Authority for any steps that he might take but he did pledge to consult with congress as he got closer to a decision.

The nfls Washington Redskins say this morning they will fight the newest threat to the teams controversial name and logo. The u. S. Patent office cancelled the teams trademark registration wednesday. A judge ruled the longtime nickname insults native americans. Jan crawford is at fedex field in landover, maryland the redskins home stadium. Jan, good morning. Reporter good morning, charlie. This ruling does not mean that the redskins are going to have to change their name but at some point it could affect the teams bottom line and the control it has over its merchandise. On the practice field, the Washington Redskins tried to stay out of the controversy over the name and logo they were wearing. Thats way over my head man. I cant comment on that. Our job as players is to focus on what we can on this field day in and day out and let the league and people take care of that stuff. Reporter but the governments decision to cancel the redskins trademark rocked the sports world and sent washington fans into a frenzy of speculation. Is this the beginning of the end for the name of the Football Team . I mean you would have to assume so. Reporter or maybe not. Its rare for the government to cancel a trademark because a group finds it derogatory, and the redskins have fought this battle before. The Trademark Office made a similar ruling against the team 15 years ago. The organization appealed and won. The Team Attorney predicted the same outcome this time saying we are confident we will prevail once again. That legal battle could take years, and even if the team eventually lost trademark experts say it has other legal avenues to keep people from selling unlicensed merchandise. I would not take this as a green light to go out there and start printing fake redskins jerseys and going out and selling them. Reporter but the ruling is likely to increase pressure on the team politically. In congress 50 senators have signed a letter urging the redskins to find another name. Even former players say the ruling could signal a name change is inevitable. If it were to change i would totally understand why and i think that the fan base would understand why. I think it might take a little bit of time for a lot of diehards to get over the whole change, but i think that its such a strong fan base that they would adjust. Reporter now, the government cancelling trademarks because some people find the name offensive does raise some free speech concerns, and then what about those other teams that have native american nicknames like, say, the golden state warriors. This could set up a First Amendment fight that many are predicting the Supreme Court eventually will have to resolve. Jan, thanks. New research this morning finds a single gene may be critical to lowering your heart attack risks. Two medical studies identified a gene mutation that affects indicators of heart health. Our dr. David agus is in los angeles. Doctor, good morning. Good morning, charlie. Tell us more about what these studies tell us. For the last 30 years the way weve treated Heart Disease is by lowering ldl, which we called the bad cholesterol. Now two separate papers in the new england journal of medicine two studies show that triglycerides were just as important. People who had a mutation in one gene called apoc3 this gene was meant to keep triglycerides up. When its mutated or turned off, triglycerides go down and Heart Disease go down pretty dramatically in these people. So we now have for the first time a new target to prevent or delay Heart Disease. So if they can figure out how to duplicate this mutated gene then theyre a long way to preventing heart attacks . No question about it. Theres a drug now in involvement that hits this gene and turns it off and lowers triglycerides in patients. We have yet to see whether it prevents heart attacks, but theres a lot of hope. This is fascinating, doctor because we know that heart attacks are the leading killer in the United States. We currently have statins, which help, but there hasnt been a new drug for decades, right . No question about it 600,000 deaths a year. We now have something we can target. And its really exciting how they came about. Historically in medicine we throw out the outliers. The fids ixphysics look at the outliers. Theres a group of amish that had very low triglycerides and low Heart Disease. When they would eat a milk shake their triglycerides wouldnt go up. It was shown in these people this particular gene and we know the exact mechanism and can target it. All right thank you so much doctor. And a Southwest Airlines jet landed safely after hitting a flock of birds near tampa. The birds hit the jets left wing after taking off yesterday morning. The jet was about four miles from the airport on its way to houston. The plane returned to tampa. No one was injured and the passengers were rebooked on other flights. This morning the faa is rolling out long awaited air traffic technology. It promises to make air travel in and out of the nations busiest airports safer and more on time. Transportation correspondent jeff pegues is at Reagan National airport outside washington. Reporter good morning, and good morning to our viewers in the west. The next generation of air travel is something that lawmakers and federal regulators have talked about for some time. Now the flying public is expected to see and feel the difference for the first time. The air Traffic Control center in the houston metropolitan area will be the first of 14 Locations Nationwide to implement an airspace overhaul known as next gen. Its part of the federal aviation administrations plan to transition air Traffic Control from radar to satellite. Anthony foxx is the secretary of transportation. We are always looking for ways to improve safety in our airspace. And we think next generation technology, next gen, is going to do that. Its going to do that because we can track the planes more precisely. Its going to do it because planes will ultimately have more awareness of other planes in the airspace. Reporter using satellites will let planes fly more direct routes. The technology is expected to cut airlines costly fuel consumption by as much as 3 million gallons a year. Passengers may notice the difference by listening to the sound of the engines when a plane comes in for a landing. Currently on approach planes level off at certain points. Next gen in the houston area will now enable pilots to almost idle the engines while a plane descends at a steady rate. The faa compares it to sliding down a bannister. Major Airlines Support the airspace redesign and have spent hundreds of millions of dollars incorporating the new technology into their planes. But earlier this month, dave barger the ceo of jetblue, expressed concerns that the faas next gen overhaul wasnt moving fast enough. I think there has been progress. We can talk about progress. But we need progress quicker, faster. Its just the technology is there. We need to move it forward. Reporter takeoff for next Gen Technology has been bumpy. According to an Inspector General report released earlier this year found performance short falls as well as cost increases. But the faa is moving forward. Theyre phasing in the technology. They say that is a process that will take a decade and youll see this technology in california. Jeff thank you. One of the favorites has fallen at the world cup in brazil.
