Norah norah . Megan, thank you. And the filibuster has played a huge role in the history of the senate. This morning that power of openended debate has been dramatically cut back. Senate democrats voted yesterday to change the rule that allowed republicans to block president ial appointments. Senators will only be allowed to Filibuster Supreme Court nominations. Nancy cordes is on capitol hill. Nancy, good morning. Reporter good morning to you and to our viewers out west. The rule they changed has been around for 96 years. Democrats argue republicans were abusing it so they had no choice, while republicans call this a power grab that robs the minority of one of its few true pieces of leverage. All but three democrats voted to clip the minoritys power, lowering the hurdle for confirming president ial appointees from 60 votes to a simple majority of 51 votes. That means republicans can no longer block nominees if they dont like them or to extract unrelated confessions. What is going on is absolutely unfair and wrong, and im glad we changed it. Reporter half of all the filibusters against president ial nominations in u. S. History have involved mr. Obamas nominees. 76 president ial nominees are awaiting confirmation for an average of 147 days. Republicans recently blocked three of the president s nominees to the powerful u. S. Circuit court of appeals in d. C. But republicans say democrats are only taking this step now because theyre trying to divert attention from obama cares problems. Id say to my friends on the other side of the aisle, youll regret this, and you may regret it a lot sooner than you think. Reporter thats the same argument thensenator barack obama made in 2005 when republicans were in charge and considering the same move. I think the loss will be enormous and one that all parties involved will come to regret. Reporter on thursday, he said times have changed. Todays pattern of obstruction, it just isnt normal. Its not what our founders envisioned. Reporter republican senator john mccain led a bipartisan effort to head off the Nuclear Option in july. He was not successful this time. Do you think the senate can ever go back . From this . I would be surprised because if we got the majority in 2015 i think there would be people who would be not want to reverse it. Reporter democrats say this move will ease gridlock because theyll be able to get these nominees through much more quickly, but republicans say its only going to increase mistrust on all the other issues. Either way no ones getting confirmed over the next two weeks, norah and charlie, because the senate has just gone on a long thanksgiving recess. Nancy thank you. The dow opened about 40 minutes ago in record territory. For the first time the Dow Jones Industrial average started the day above 16,000. It picked up 109 points thursday to close at 16,010. 2013 is a good year for investors. The dow has gained 22 . The nasdaq is up 31 . And the s p 500 has added almost 26 . A notorious murder case in the 1970s is taking a new turn. Michael skakel is free on bail this morning after spending 11 years in prison. Robert f. Kennedys nephew has insisted for decades that he did not kill a teenage neighbor. 48 hours correspondent troy roberts has covered this case for years. Troy, good morning. Good morning, norah. It was a trial that made headlines. A kennedy cousin convicted of a brutal murder. Then last month a connecticut judge threw out that conviction. Yesterday he found out he could await his new trial from outside prison walls. Reporter this is Michael Skakel as a free man. For the first time in 11 years. On thursday a connecticut judge set skakels bond at 1. 2 million. As he exited the courtroom, he gestured to his family who burst into applause. Skakels attorney, Hubert Santos saw todays decision as righting at least one wrong from the past. There were two tragedies that occurred in greenwich, connecticut, in 1975. The first was, of course the murder of martha moxley. The second great tragedy occurred in a courthouse in norwalk, connecticut, in 2002 when michael was convicted of the murder of martha moxley. Reporter in 2002 skakel was sentenced to 20 years to life in prison for the murder of martha moxley. In 1975 she was found beaten to death under a tree in her suburban connecticut backyard. Skakel and moxley had been neighbors. Both were 15 years old at the time. Through the years, skakel now 53 years old, maintains his innocence. I did not commit this crime. Reporter as did his family. Skakel is the nephew of Ethel Kennedy and the kennedys rallied to his defense. Robert f. Kennedy jr. Is skakels cousin. Hes been in prison for a decade for a crime that he didnt commit. Reporter last month a judge agreed with skakel that he did not receive an adequate defense from his trial lawyer mickey sherman. But outside the courthouse on thursday, dismay from the family of martha moxley. Her mother dorothy, was a constant presence at skakels hearings. Im disappointed, but this is life. Reporter and marthas brother, john moxley says that wont change any time soon. Were not going away. We think the court got it right the first time, and were not going away. As per the conditions of his bail skakel cannot leave the state without permission and must wear a tracking device. Now hell await news of his retrial. Charlie . Norah . Thank you troy. More changes could be coming to your airline flight. Next month the government will consider letting travelers talk on their cell phones while in the air. The use of mobile phones would be allowed once a plane reaches 10,000 feet but not during takeoff or landing. Cbs travel editor Peter Greenburg is with us. Good morning. Good morning. Tell us what this means. Skbloo with the fcc will now consider this rule in fact change it as you said above 10,000 feet people can make calls if the airline wants to be part of this deal. If they do want to be a part of it theyd have to install a cell phone base station on the plane. Right now technically you really cant get a signal from your own cell phone that will be effective below 10,000 feet or even above 10,000 feet. Sounds like a good idea for customers. You know, you can make a call from a plane, but apparently the association of flight attends said passengers making phone calls could extend a mere nuisance creating negative effects on aviation safety and security that are great and far too risky. You think thats true . The technologys already there. Its been there for quite some time. Weve had had air phones on planes before. Its a social issue. You have so much ambient noise inside that for you to actually have a reasonably decent conversation with somebody, you almost have to yell. Now, do you really want that happening with the person sitting next to you . Do the flight attendants want inflight flights . I dont think so. Yeah, loud talkers. In terms of cost will it make any difference . Remember, if you have to put that base station on the plane, the airlines going to want revenue. You have roaming charges on the ground. Imagine what they could be in the air. Now, some airlines have already said theyre going to do it or at least consider it if the fcc does remove the rule. They said theyd entertain the idea. Delta said absolutely not. Feedback is so overwhelmingly. Were going to continue the policy of not allowing conversations on board. Wifi. Wifi is different. How long do you think it is before we could see this actually take effect on some airlines . Well, remember, you still have to install those cell phone bay stations. That means theyll take each plane out of service to do it. Youre talking maybe march, april, may of next year. Thank you. And negotiations to curb Irans Nuclear program continue this morning in geneva. For a third day, top diplomats are hammering out the sticking points of an agreement, but there is pressure coming from the u. S. Harry reid is preparing to move ahead for plans to impose new sanctions against iran. Margaret brennan is at the state department this morning. Margaret, good morning. Reporter good morning. And good morning to our viewers out west. Well pressures on those negotiators in geneva to hammer out a deal by the weekend.

Iranian negotiators are looking for more Financial Relief from sanctions that the u. S. And world powers are offering. Raising concerns about a potential deal. Im not in a position to go into the details of that but we have some major differences still. And those differences are on every side almost. Reporter iran agreed to the Nuclear Talks because its economy is in desperate shape. U. S. Led sanctions have cost it 120 billion in oil sales and slashed the value of its currency. The treasury departments david cohen helped enforce those sanctions. The whole idea behind the sanctions from the outset was to create leverage and move away from where it has been proceeding with its nuclear program. Reporter but first, iran and world powers will have to agree on how much money is on the table. The u. S. Froze 100 billion worth of the regimes assets. The iranians want access to that money. For now, iran is being offered under 10 billion in sanctions relief if it signs a sixmonth deal to slow its nuclear program. The Administration Says less than 10 billion. Why is it worth it . Well the relief package, youre exactly right, is actually quite modest. Its limited, and its reversible. Reporter for skeptics like the israelis and many in congress, it is too soon to reduce pressure. But cohen says the u. S. Will continue to track irans money and enforce the most damaging sanctions. I am going to go around the world, and my partners will go around the world to be very clear that anybody who acts in a way that violates any of the remaining sanctions will be dealt with. Reporter the u. S. And iran have not yet had substantive oneonone negotiations in this round of talks.
