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 dropby.

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.

Jim axelrod, cbs news, new york. And thats the overnight news for this thursday. For some of you the news continues. For others check back with us just a little bit later for the morning news and cbs this morning. York city, im scott pelley. Announcer this is the cbs overnight news. Welcome to the overnight news. Im don dahler. Vice President Joe Biden has made it official. He will not seek the democratic nomination for president. His announcement ends months of speculation. Heres what he had to say. Mr. President , thank you for lending me the rose garden for a minute. Its a pretty nice place. As my family and i have worked through the grieving process, ive said all along what ive said time and again to others, that it may very well be that that process, by the time we get through it, closes the window on mounting a Realistic Campaign for president. That it might close. Ive concluded it has closed. I know from previous experience that there is no timetable for this process. The process doesnt respect or much care about things like filing deadlines or debates and primaries and caucuses. But i also know that i could do this i couldnt do this if the family wasnt ready. The good news is the family has reached that point. But as ive said many times, my family has suffered loss and i hoped there would come a time, and ive said this to other families, that sooner rather than later when you think of your loved one it brings a smile to your lips before it brings a tear to your eyes. Are today, thank god. Beau beau is our inspiration. Unfortunately, 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. I intend to speak out clearly and forcefully, to influence as much as i can where we stand as a party and where we need to go as a nation. And this is what i believe. I believe that president obama has led this nation from crisis to recovery and were now on the cusp of resurgence. Im proud to have played a part in that. This party, our nation, will be making a tragic mistake if we walk away or attempt to undo the obama legacy. The American People have worked for that. Democrats should not only defend this record and protect this record, they should run on the record. Vice President Joe Biden. On capitol hill republican congressman paul ryan is singing a different tune. After weeks of refusing calls to run for speaker of the house, ryan now says hes open to the job but he has conditions. Nancy cordes has the story. Reporter first and foremost, ryan says that all t different wings of the House Republican conference must endorse him by friday or he wont run. That turns the tables on hardline conservatives who were hoping to extract concessions from their next speaker in exchange for their support. What i told members is if you can agree to these requests and if i can truly be a unifying reporter ryan laid out his republicans and then for the press, starting with a call for the gop to start focusing on solutions. We need to move from an Opposition Party to being a proposition party. Reporter then he said the house rule book must be changed. And it needs to include fixes that ensure that we do not experience constant leadership challenges and crises. Reporter the last request was personal. I cannot and i will not give up my family time. I may not be on the road as often as previous speakers, but i pledge to try and make up for it with more time communicating our vision, our message. Reporter most House Republicans were happy to oblige after begging the father of three to take the job. There was overwhelming applause. I didnt see anyone booing. Reporter one candidate in the speakers race promptly dropped out. Im out, and im in with paul. Hes the right person at the right time. Reporter ryans unusual approach is a reflection of his strong leverage. As a conservative whos also cut deals with democrats, hes seen as one of the only people who can unite his fractured party after hardliners threatened to force out the current speaker, john boehner, and doomed his replacement, kevin mccarthy. Ryan warned them, as speaker he would work with the other side. My greatest worry is the consequence of not stepping up. Of someday having my own kids ask me, when the stakes were so high, why didnt you do all you could do . Why didnt you stand and fight for my future when you had a chance to do so . Reporter ryan says if the entire party doesnt get behind him by friday he will happily stay in the job he has. And it puts the hardliners in a situation where theyll get blamed if he backs out. Ironically, gale, that is exactly what they say theyve been wanting from the next speaker, a hardball approach. Police in st. Louis still have no suspects in a rash of fires at predominantly black churches. Six churches have been burned over the past two weeks. They are all within five miles of each other and stand on the doorstep of ferguson, missouri. Ferguson, as
