Good evening. In the face of an unfolding crisis that has been leaving tens of thousands of children at this nations southern doorstep, president obama tonight is preparing an urgent request to congress to help stem the human tide. The current flood has never been bigger. 52,000 unaccompanied kids come along the border since october along about 39,000 families with children. All at a rate of 12 to 1400 migrants a day. Officials say most are coming from central america. Tonight the white house saying it needs money and the tools to speed deportations. Kristen welker is standing by with details. Good evening. Reporter lester, good evening. The president s request for new funding is the latest move by the Obama Administration to deal with the crisis along the border. The president is under increasing pressure to tackle the issue but with relations already deeply strained between this president and republicans on capitol hill, there are no guarantees. With unprecedented waves of undocumented children crossing the southwest border every day, a strong warning from the president do not send your children to the borders. If they do make it, theyll get sent back. More importantli, they may not make it. Reporter tomorrow, president obama will ask congress forred 2 2 billion in emergency funds and seem expanded authority for the dhs secretary to fast track defor trags procedures and stiffer penalties for those who snuggle children across the border. But for the children who have already made it across . We have to house the kids and take care of them until the machinery under current law allows us to send them back. Reporter that law signed by president george w. Bush in 2008 states children cannot be sent back. They must be held humanely until the courts release them to a situation that is deemed safe. Immigration groups argue that president obamas attempts to speed up deportations could further endanger children. What were concerned this will result in is children really being sent back to very dangerous situations. It seems it would be a significant rollback of our both our responsibility and our leadership. Reporter and there is bipartisan agreement that more needs to be done to secure parts of the border. Its a crisis like nothing ive ever seen before at the border. We have refugee camps now. I dont think the flow will stop until a message is sent back to central america. Its a humanitarian crisis that were facing down there. But at the same time, its issues about homeland security. Reporter the question now will congress approve the president s request . Given how gridlock this congress is, i dont think that congress is going to give him, president obama, a blank check on this one. Reporter a spokesman for john boehner says he wont react until he sees the proposal. A white house official says tomorrow president obama will nominate bob mcdonald, the former ceo of Procter Gamble to be the next va secretary, a veteran and west point graduate. He replaces eric shinseki. Kristen welker, thanks. Government forces continue their offensive today in iraq with help from the u. S.
