Nearly 50year political career. With president obama at his side, the Vice President announced he will not make a third run for the democratic nomination in what would have been an uphill battle against Hillary Clinton. Major garrett broke the story today, and he begins our coverage. I believe were out of time, the time necessary to mount a Winning Campaign for the nomination. But while i will not be a candidate, i will not be silent. Reporter joe biden stood with president obama and said the democratic nominee should stand on their accomplishments. Democrats should not only defend this record and protect this record. They should run on the record. Reporter but mostly, biden framed an agenda for a campaign that was not to be. We cannot sustain the current levels of inequality that exists in this country. I believe the huge sums of pouring into our politics is a fundamental threat to our democracy. Reporter he also made a plea for bipartisanship and took a veiled swipe at Hillary Clinton after she halfjokingly called republicans her enemies during this months president ial debate. I dont think we should look at republicans as our enemies. They are our opposition. Theyre not our enemies. And for the sake of the country, we have to work together. Four more years of this kind of pitched battle may be more than this country can take. Reporter after losing his son, beau, to brain cancer earlier this year, bidens decision on whether to enter the race hinged largely on his familys emotional readiness for a campaign. Today, he called for an ambitious assault on the disease that claimed his son. If i could be anything, i would have wanted to be the president that ended cancer because its possible. Its personal, but i know we can do this. Reporter biden, ever with a note of optimism that left many friends and supporters wondering what might have been. Its about equality. Its about fairness. Its about respect. As my dad used to say, its about affording every Single Person dignity. Its not complicated. We can do this. And when we do, america wont just win the future. We will own the finish line. Reporter despite president obamas affection and respect for biden, he had grown restless with the Vice President s prolonged president ial deliberations and, scott, mr. Obama was more than mildly pleased to see the speculation and the distractions that came with it laid to rest. Pelley Major Garrett at the white house, major, thanks. Now lets bring in john dickerson, our cbs news political director and anchor of face the nation. John, what struck you about the Vice President s statement . Reporter you know at one point in his remarks he thanked the reporters who had been covering his deliberation process and quickly added, and covered my whole career. It was a subtle acknowledgment of a larger point which was biden wasnt just putting an toapped this president ial process. He was marking whats likely to be the end of his career in washington. It started in the early 70, and as if to harken back to that he made that pitch that major talked about for bipartisan isship with republicans. It would have been interesting to see if he could have campaigned on that. That was not the mood of his party right now. Pelley tomorrow Hillary Clinton will be testifying on the attack on the compound in benghazi, libya, and no doubt questions about her private email server. What are the stakes for her . Reporter she had a lot of big hurdles to clear in october, and there were those she could control and those she couldnt. The debate was one hurdle, and shes cleared that. Joe bidens possible candidacy was another hurdle, which has now been cleared away for her. Tomorrow is really the last big test for her in october. Can she of weather a full days worth of testimony in front of a republicans have said is aiming to hurt her politically. If she can do, that she will be on stable ground after what was a pretty shaky summer. Pelley and well be watching face the nation on sunday. John, thanks very much. Were about to find out if one man can unite republicans in congress. Many in the house are begging congressman paul ryan of wisconsin to be the new speaker, and last night, the reluctant ryan said he would do it but only if all the the factions support him. Ryan was the g. O. P. s 2012 candidate for Vice President. Hes an expert on the budget and chairs the waitz and means committee, which writes tax policy. Will his ultimatum work . Heres nancy cordes. Reporter paul ryan spent the day meeting with conservatives who didnt know quite what to make of his takeithoarleaveit approach. There were a list of pretty strong demands. Reporter ryan says he will only run for speaker if all the wings of the fractured republican conclude endorse him by fridays, and if hardliners agree not to constantly threaten boehners. We have become the problem. If my colleagues entrust me to be the speak ei want us to become the solution. Reporter idahos Raul Labrador didnt like the sound of that. It appears hes asking for more power to be in the Speakers Office instead of less power. Reporter even this condition met with some resistance i cannot and i will not give up my family time. Reporter congressman Tim Huelskamp of kansas what did you think of his request to spend most weekends with his family . I dont think the speakership is a 95 job. Ive got family and thats why im not running for speaker or any other position like that. You have to work on the weekends. Reporter ryan has pushed for deep cuts in food stamps, housing assistance, and proposed converting medicare into a voucher program. We want to have real fiscal control. Reporter most republicans Speaker Boehner signaled today ryans the only viable option. Whats plan b if he doesnt decide to jump in on fridays . Dont know. Reporter dont know. Ryans hardball approach may not be sitting well with some of the hardliners but it is the kind of Strategic Thinking theyve been saying they want in a speaker. And its all in their hands now, scott, because ryan will not be able to get the 218 votes he would need on the house floor next thursday unless at least some of them it support him. Pelley and ryan has also worked effectively with democrats. Nancy cordes on capitol hill. Nancy, thank you. Another politician who wants things on his own term is russian president Vladimir Putin, who has now gone to war to save syrian dictator bashar alassad. Last night, assad showed up unexpectedly in moscow, the first time hes left home since a rebellion broke out four years ago. Mark phillips now on putins game plan. Reporter this was a lot more than just a courtesy dropby between old friends. It was a thanks for everything, and i mean everything, drop. By. Vladimir putins jets are now effectively bashar alassads air force. That may explain the smile. And that air force was in it action during the meeting. The russians say they hit 83 targets over the past day, including these two strikes on what moscow claims were a rebel leaders Meeting Place and a logistics camp. Theres no longer and pretense of only hitting isis targets. Most russian attacks have been on assads other enemies, including rebels supported by the u. S. And the airstrikes have another purpose theyre it bombing russia back to being a major player in the middle east. Vladimir putin is now running the diplomatic show as well, telling assad the bombing must be followed by peace talks. And putins been working the phones. Recep tayyip erdogan, after the meeting, and he called another major player, king salman of saudi arabia, as well. The welcome afforded assad in moscow, including a gilded kremlin dinner, was clearly designed to show russias unwavering support for him. In the west, the syrian president may be irreparably damaged goods, who the u. S. And others say must go, but hes still moscows man. And, scott, the clearest sign that Vladimir Putin has his own agenda and is now a powerful independent actor on the syrian issue no one in the u. S. Government had a clue about the assad moscow visit until after it happened. Pelley Mark Phillips in our london newsroom. Mark, thank you. We noticed a study today by the World Health Organization that said that longterm exposure to radiation, even at low levels, can dramatically increase the risk of dying from cancer.

Radiation barriers were installed as a bandaid solution in 2013. Michael feldmann with the army corps of engineers says the cleanup moves slowly for a reason. In general, there are things we need to do at the pace we are performing in order to make sure that we are protecting the health and the environment of the area. Reporter dr. Fasial kahn is the director of Public Health in st. Louis county. Some disasters unfold slowly over time, and their true nature and extent and severity only becomes clear in terms of human cost once you start counting people around you.

Reporter all of the residents in north st. Louis with Health Issues tell us they believe they had longterm exposure to the lowlevel contamination.
