Theyd be carried out on a stretcher, folks. Reporter all of it drove marco rubio to this 11th plight. 70 to 65 of republican have already decided they dont want donald trump as their nominee. As long as that vote is being divided up among multiple people, its good for donald. Reporter appalled by the street fighting over second place between rubio and ted cruz, some in the conservative establishment said today its time to take down the frontrunner. In an urgent call for donations to directly attack trump, a superpac, largely funded by the family that oppose the chicago cubs, expressed the worry that, we are about to nominate a candidate who shares none of the values of our party has held lead our party to general election ruin in november.

She met with them privately, scott, in chicago in november to gain their support. Pelley nancy cordes, thanks. Well, in a break with history today, the Republican Leadership said the senate will not consider any nominee to the supreme court, no matter who it is. President obama is preparing to name his choice to replace the late antonin scalia. But the republicans say that seat should remain empty 11 months awaiting the next president. The senate has always given a nominee a hearing since at least 1875. Heres chief Legal Correspondent jan crawford. There should not be a hearing anyone that the president nominates. Reporter senator john cornyn and the 10 other republicans on the Judiciary Committee explained in a letter to Senate Majority leader Mitch Mcconnell that the decision was based on constitutional principle and born of a necessity to protect the will of the american people. Democrats, like Judiciary Committee member chuck schumer, called the move unprecedented. But to not even give the nominee a hearing and fair consideration is beyond the pale, and it wont stand. Reporter stand. But republicans said democrats laid the groundwork after years of delaying hearings and block g. O. P. Nominees and they point to the words of thensenator joe biden discussing a possible vacancy in 1992. The senate Judiciary Committee should seriously consider not scheduling confirmation hearings on the nomination until ever until after the Political Campaign reporter now, mcconnell again today said he saw no point in even meeting with the president s eventual nominee. And, scott, the white house pointing to 1875 as the last time a nominee failed to get a hearing or a vote. Pelley jan crawford on capitol hill. Jan, thank you. And republicans had essentially the same reaction today when the president proposed closing the guatanamo bay prison for terror suspects by the end of this year. Guatanamo opened in 2002 on the u. S. Naval base in cuba, which allowed prisoners from afghanistan and elsewhere to be held without charges or trials. 779 prisoners have been held there, but today, 91 remain. Margaret brennan is at the white house. The politics of this are tough. Reporter tough politics because the president s proposal involves bringing nearly 60 guatanamo prisoners to the United States. Were already holding a bunch of really dangerous terrorists because we threw the book at them, and there have been no incidents. Reporter of the 91 prisoners remaining at guatanamo, 35 would be transferred to other countries, 46 held in the u. S. Under military guard, and at least 10 would face trial in criminal or military courts. That includes socalled 9 11 mastermind sheikh mohamed, who has never been convicted during his 13 years in u. S. Custody. Pentagon officials have looked at more than 13 locations in the u. S. For housing the prisoners, including the naval brig in south carolina, a Supermax Prison in colorado, and the military prison in leavenworth, kansas. But in 2011, congress made it illegal to transfer guatanamo inmates to the u. S. And republicans in congress are almost universally opposed to changing that law. Kansas senator pat roberts made his opinion clear today. This is what i think of the terrorists to the United States. Reporter so did colorado republican congressman mike coffman. He knows that in fact the will of congress is not going to change, that we are not going to amend existing law, that would in fact allow these detainees to come to u. S. Soil. Reporter president obama said that closing guatanamo will save taxpayers tens of millions of dollars and, scott, the white house today would not rule out taking executive action to shutter the prison if congress does not act. Pelley margaret, thanks. Now, margaret just mentioned Khalid Sheikh mohamed, charged with planning 9 11. He was captured by u. S. Forces in pakistan in 2003, and for the most part hes been at guatanamo bay since. His case is in a military court there. Lawyers have filed more than 200 motions, many of them claiming abuse and torture, and after more than a dozen rounds of still likely years away. President obama held a Video Conference today to brief european heads of state on the ceasefire plan for syria that is supposed to begin on saturday. But that agreement does not include isis, which holds about a third of syria, or the al qaeda affiliate there known as alnusra. It is rare for a western reporter to get into syria, but Elizabeth Palmer is there in damascus tonight. Liz, what are you learning about the prospects of the ceasefire . Reporter well, i had the unusual opportunity of talking to two syrian Army Officers today, and both of them said personally, they had no appetite for a ceasefire. They were gaining ground on several fronts at the moment. They didnt want to lose momentum. One of them had just returned from officer training in moscow mean had his russian certificate proudly displayed on his bookshelf and he said quite frank lets russians are calling the shots. Observe a limited truce here or there, well do it. As for the opposition, both of them were deeply scornful. They said most of the opposition groups dont have enough discipline to actually adhere to a ceasefire. Theyre constantly morphing, changing their names, changing their tactics, even changing their leaders. Pelley and secretary kerry in the United States said today he wasnt sure the ceasefire was going to work, either. Elizabeth palmer in damascus for us tonight. Liz, thank you.

Angelica is due in april and so far, so good. Scott, you may be wondering why every day theres new information about zika. Remember, 10 years ago, this infection was almost unheard of. Now its exploding and being gang tagled by the scientific community. Pelley john, thanks very much. Up next, apples fight for privacy. What about my family . My lil buddy . And what if this happened again . I was given warfarin in the hospital but i wondered if this was the right treatment for me. Then my doctor told me about eliquis. Eliquis treats dvt and pe blood clots and reduces the risk of them happening again. But eliquis also had significantly less major bleeding than the standard treatment. Knowing eliquis had both. Turned around my thinking. Dont stop eliquis unless your doctor tells you to. Eliquis can cause serious and in rare cases fatal bleeding. Dont take eliquis if you have an artificial heart valve or abnormal bleeding. If you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. While taking eliquis, you may bruise more easily. And it may take longer than usual for bleeding to stop. Seek immediate medical care for sudden signs of bleeding, like unusual bruising. Eliquis may increase your bleeeeng risk if you take certain medicines. S. Tell your dodoor about all planned medical or dental procedures. Eliquis treats dvt pe blood clots. Plus had less major bleeding. Both made switching to eliquis right for me. Ask your doctor if its right for you. Every Auto Insurance policy has a number.
