good evening. in the face of an unfolding crisis that has been leaving tens of thousands of children at this nation's 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, they'll 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 obama's attempts to speed up deportations could

further endanger children. >> what we're 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. >> it's a crisis like nothing i've ever seen before at the border. we have refugee camps now. i don't think the flow will stop until a message is sent back to central america. >> it's a humanitarian crisis that we're facing down there. but at the same time, it's issues about homeland security. >> reporter: the question now -- will congress approve the president's request? >> given how gridlock this congress is, i don't think that congress is going to give him, president obama, a blank check on this one. >> reporter: a spokesman for john boehner says he won't 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. to take back at least one city from sunni insurgents that control a big partst country right now. nbc's chief foreign correspondent is following it all from baghdad. hello, richard. >> reporter: good evening, lester. the u.s. is now providing more military advice and more weapons. but it racky government has a major challenge on its hands. there rat least 10,000 figer fi from the militant group and they

proved they have global ambitions. iraqi forces have secured the highway between somara and baghdad. and roads leading to tikrit. it's the iraqi military's first achievement against the militants in weeks. the advance helped by a new u.s. shipment of hellfire missiles. american advisors are also giving the iraqi military intelligence and tactical advice. and warnings, too. cautioning the iraqis not to push too far too fast and not to try to take back major cities and be drawn into urban battles. but isis is sending its own reinfor reinforcements to tikrit and show them in another video. this fighter says he is explains how the militants freely move across the border between syria and iraq. >> iraq, jordan, sudan, all the

countries. >> the base is the syrian city of raqqa. from there, the militants have a direct supply line to their iraqi strong holds in mosul and fa luge yachlt the militants have carved out a safe haven and today declare the rebirth of the islamic empire founded in the seventh century. the militants called on all muslims to swear allegiance to their leader, a former u.s. prisoner in iraq who has said he'll carry out attacks against the u.s. bigger than those of osama bin laden. >> it's more rough there and higher. we're fighting to make the world of the highest. >> it is now fighting in the middle east but today the group made it clear that its ambitions are far greater than that. the political instability here is certainly not helping the government's fight against the militants. next week here in baghdad, the iraqi parliament is set to convene to try and put a new

government together. and there are growing calls for prime minister maliki to step down, some of them even from members of maliki's own coalition. lefter? >> all right. thank you. back in this country, we're following severe weather tonight especially in the midwest where they've been struggling for days with the worst flooding in decades. and another big storm is moving east tonight. we get the latest from berth channel meteorologist chris warren. >> reporter: summer storms brought more rain to the midwest this weekend. in already water logged minneapolis, a line of storms swept from west to east, triggering flash flood warnings in nearly every county in the region. >> stay on this side of the street. >> reporter: water deep enough for this resident to paddle through a flooded intersection n waterville, the minnesota governor toured the damage. >> i have never seen damage this severe and widespread. usually it's in one or two down theies. >> reporter: leaving close to 8,000 people without power.
