this is the "cbs evening news" >> cordes: good evening, i am nancy cordes, a simmering campaign over outsourcing has boiled over with the president's campaign and mitt romney's accusing each other of lying about romney's record at the helm of bain capital. the fight is notable for how personal and antagonistic it has become nearly four months before voters cast the ballots in the presidential election. >> wyatt andrews is in washington tonight with more on what the president said today and who, if anyone, is telling the whole truth, wyatt. >> reporter: nancy, despite mitt romney's personal demand for an apology, the president's campaign again said it is not happening, in fact, the president doubled down on charges that romney was in command at bain capital when bain took over companies that were outsourcing american jobs. >> campaigning in richmond in a cool, pouring rain, the president heated things up on the issue of outsourcing. >> i don't want to pioneer in

outsourcing. i want some insourcing. i want to bring companies back. >> oh, beautiful, for spacious skies -- >> the president's campaign also issued a new attack add mocking romney's stinging and accusing him of sending jobs overseas. >> the ad drew a tough response from the romney campaign every day the statement said president obama hits a new low. >> romney relaxed at his lake house with family today, but yesterday denied the outsourcing claim. >> in several interviews, concluding one with cbs news correspondent jan crawford romney says he left bain well before control several companies downsizing in america. >> i had no involvement with the management of bain capital after february of 1999. >> however, bain's public filings with the securities and exchange commission after 1999 repeatedly list romney as sole shareholder, sole director, chief executive officer,

president, and even managing director. still, rom my is adamant he did not manage bain at the time. but the obama campaign charged that romney was either misrepresenting his position at bain to the sec, which is a felony .. or misrepresenting his position at wayne zero -- at bain to the american people. it was essentially calling romney a criminal or a liar. >> what he wants to do is try to divert the attention from his lack of success and frankly, it is beneath the dignity of his office, he ought to apologize for what he is doing. >> reporter: outsourcing is a major swing state issue, so the stakes in winning this are high, romney argues you can be a ceo and still not manage a company, but nancy, the president argues when you are an owner and ceo you are still responsible. >> wyatt andrews in washington tonight. thanks. >> cordes: turning overseas, un observe her teams says it found signs of targeted assa urn to

regime, which jailed members of the muslim brotherhood, including mohammed morsi himself. >> so the exchange they said was constructive and one state of beneficial told me it lasted around an hour, the president shook the secretary's hand and told her the expectations of the egyptian people are high, there is no going back, i am told in particular they had a fooled exchange on the economy. they need u.s. aid right now and trade. there was positive feedback on a proposal that business executives here as part of job creation, this country's double digit unemployment. >> cordes: margaret the u.s. government has given egypt military $1.3 billion this year alone but the officials are not happy with some of the things the generals have done so what is secretary clinton's message to them? >> she is going to tell field marshall that the military must return to a national security role, that means stop this conflict over the constitution and the parliament, go back to

negotiation might actually make things better. >> that threat of an additional charge could hurt business. >> don't ever underestimate the anger of the american public when they feel that one is unfaily making money off of them. >> reporter: the question is if those swipe fees go down, will retailers actually pass the savings on? >> are consumers going to be beige more or less as a result of this? >> no one knows. that is the reality. no one knows. >> now, a federal judge still needs to review this settlement before approving it and that could take several months. if he does approve the deal, there would be an eight month window to sort out the details, nancy. >> cordes: elaine quijano in new york for us tonight, thank you. drought conditions are plaguing much of the condition, record heat waves wild fires have kind to create the driest conditions in decades, more
