democratic presidential nominee hillary clinton received a big convention bounce. a new cnn poll has her leading gop rival donald trump 52 percent to 43 percent in a two-way matchup.









the republican nominee is still under fire for how he reacted over the weekend to the parents of humayun khan, a muslim u.s. army captain killed in iraq.









khizr khan blasted trump at the democratic convention, noting that unlike his fallen son, trump has "sacrificed nothing and no one." unwilling to the let the insult pass, trump hit back, implying that khan's wife wasn't allowed to speak during her husband's dnc address because of the family's muslim faith.









the gop nominee's remarks have sparked outrage from veterans and members of his own party.









"while our party has bestowed upon him the nomination, it is not accompanied by unfettered license to defame those who are the best among us," war hero sen. john mccain, r-ariz., said.









trump's campaign is now appealing to gop colleagues on capitol hill to help quell the controversy.









meanwhile, a mother whose son was killed in the 2012 attack on the u.s. consulate in benghazi, libya, is also speaking out.









patricia smith criticized clinton at the republican convention, noting that she has received much different treatment than the khan family.









"i was treated like dirt. i don't think the khan family was treated that way. i was treated like dirt. i was called a liar<u+2026> i don't imagine my son getting killed. i don't imagine that at all," smith said.









meanwhile on the campaign trail, clinton attacked trump's tax cut plan, and again called on him to release his tax returns.









"and while we're at it, we would like to see those tax returns wouldn't we? my husband and i put out, i think about 33 or 34 years' worth, if you're interested," clinton pointed out.









trump alleges that former presidential candidate sen. bernie sanders, d-vt., made a deal with the devil to endorse clinton.









"if he would have just not done anything, just go home, go to sleep, relaxed, he would have been a hero, but he made a deal with the devil. she's the devil. he made a deal with the devil," trump said.









there's still a long way to go until election day and many of today's controversies could easily be forgotten by november. clinton's poll bounce could fade as bounces often do, turning this into a tight race once again.
