The Note: Trump vs. Khan

— -- NOTABLES

--TRUMP DOUBLES DOWN ON CRITICISM OF KHAN FAMILY: Republican nominee Donald Trump, facing backlash over his controversial remarks about the family of slain Army Captain Humayun Kahn, continued to aggressively push back against critics this morning. "Mr. Khan, who does not know me, viciously attacked me from the stage of the DNC and is now all over T.V. doing the same - Nice!" Trump tweeted today in reference to an appearance Khizr Khan and Ghazala Khan, the parents of Humayun Kkhan, were making on the CNN program "New Day." Khizr Khan used the opportunity to praise his son, describing him as a "wonderful, patriotic, deliberate" person. He also criticized Trump's ignorance of the constitution, and said that Trump wanted "one set of rights for himself, and another set of rights for others," a comment that referred to the First Amendment.

--CLINTON SLAMS TRUMP, SAYS IT'S TIME TO PICK COUNTRY OVER PARTY: Democratic presidential candidate Hillary Clinton bashed Trump Sunday for his controversial remarks about the family of Army Captain Humayun Khan who died in Iraq and said the accumulation of Trump's controversial remarks throughout the election year made her wonder "where the bottom is."

--ANALYSIS -- ABC’s RICK KLEIN: Much of political punditry over the past year-plus has been spent debating whether Donald Trump had, finally, picked a foe he couldn’t defeat. John McCain? Megyn Kelly? A disabled reporter? A federal judge whose parents were Mexican? Heidi Cruz? The pope himself? Since Trump is still standing, one can argue he won his feuds with all of them. But taking on Khizr Khan, an American Muslim father of a slain US soldier, Trump is finding a different kind of challenge. Khan’s personal loss gives him the right to speak out. His convention speech gave him instant celebrity. Unlike the judge or the pope, he can respond publicly as he chooses. He has no overt partisan affiliations or motivations. Might this be the conflict – the first - that gets a full apology from Trump? “I don’t know where the bottom is,” Hillary Clinton said in responding to this controversy. For now, she’s happy to have Trump look for it.

LAST WEEKEND ON THE TRAIL with ABC’s JENNIFER HANSLER

CLINTON DEFENDS BEING CALLED 'CHANGE-MAKER.' Hillary Clinton defended being called a "change-maker" Sunday, despite her plans to continue with President Obama's agenda, saying she will go further than the current administration on rebuilding the economy should she win the White House, ABC’s LIZ KREUTZ notes.  "You say you're the real change agent in this campaign. But I think it's fair to say that you're building on the Obama agenda. You're not rejecting it," Fox News' Chris Wallace said, challenging the Democratic nominee in an interview on "Fox News Sunday." Clinton responded that she is offering "proven results" and plans to "build on where we are." http://abcn.ws/2aHpiC0

KAINE ACKNOWLEDGES DIFFERENCE WITH CLINTON ON ABORTION FUNDING. Democratic presidential candidate Hillary Clinton's running mate Tim Kaine has acknowledged that he disagrees with Clinton on the federal Hyde Amendment that restricts Medicaid funding of abortion. As ABC’s JESSICA HOPPER explains, Kaine, a devout Catholic, has previously said he is personally opposed to abortion but does not believe it is the government's role to intervene in a women's decision on whether to have one. Clinton has vowed to repeal the Hyde Amendment which bans the use of federal funds for abortion except in certain cases, such as rape, incest or to save the mother's life. http://abcn.ws/2ao4iO3

BILL CLINTON'S PENNSYLVANIA-MADE SHIRT TAKES CENTER STAGE AT CLINTON-KAINE RALLIES. Bill Clinton's fashion sensibility took center stage Saturday at a trio of Hillary Clinton rallies in Pennsylvania and Ohio. The Democratic presidential candidate cited her husband's Pennsylvania-made shirt, using it as a visual aid to slam Donald Trump's purported affinity for U.S.-made products and remind her supporters of the plethora of Donald Trump-branded products made overseas. ABC’s DAVID CAPLAN and LIZ KREUTZ have more on the former president’s fashion choice: http://abcn.ws/2amY4Ot

FOLLOWING TRUMP REMARKS, CLINTON CALLS ON AMERICANS TO 'STAND WITH' PARENTS OF MUSLIM U.S. SOLDIER. Hillary Clinton on Saturday called on Americans to "stand with" the parents of a fallen Muslim U.S. soldier following Donald Trump's rebuke of the couple, ABC’s LIZ KREUTZ notes. "I was very moved to see Ghazala Khan stand bravely and with dignity in support of her son on Thursday night. And I was very moved to hear her speak last night, bravely and with dignity, about her son's life and the ultimate sacrifice he made for his country," the Democratic nominee said in a statement, referring to the mother of Army Capt. Humayun S.M. Khan, who was killed in Iraq in 2004. http://abcn.ws/2azkpYH

MIKE PENCE RALLY INTERRUPTED BY PROTESTERS, A FIRST FOR THE VP CANDIDATE'S CAMPAIGN. While Donald Trump has generally responded to protesters’ interruptions by bellowing to security "get 'em out," his running mate Mike Pence has a different, more subtle approach. As ABC’s INES DE LA CUETARA explains, the Indiana governor-turned-GOP vice presidential candidate was interrupted by two protesters at a Friday rally at the University of Northwestern Ohio Events Center in Lima, Ohio, about seven minutes into his speech. http://abcn.ws/2ab7729

TRUMP SAYS HE HAS ONE OF THE 'BEST TEMPERAMENTS' OF ANY PRESIDENTIAL CANDIDATE. Republican nominee Donald Trump says that he's refusing to play "nice guy" anymore. As chants of "Lock Her Up" rang out at his rally in Colorado Springs Friday-- a rallying cry against Hillary Clinton -- Trump seemed to agree with them."You know what? I’ve been saying-- I’ve been saying let’s just beat her on November 8th, but you know what? No. no. You know what? I’m starting to agree with you," he said, a departure from the demurral he usually gives when the chants break out. ABC’s CANDACE SMITH and RYAN STRUYK have more: http://abcn.ws/2ajBbbi

IN CASE YOU MISSED IT

DEMOCRATIC VP CANDIDATE SHOWS HIS MUSICAL CHOPS. Hillary Clinton's running mate, Virginia Sen. Tim Kaine, can add another job title to his resume: DJ. On a campaign bus on a swing through Ohio, ABC’s JESSICA HOPPER notes, Kaine has put himself in charge of the entertainment during slow periods. http://abcn.ws/2adCLMk

WHO’S TWEETING?

@SenatorCollins: No one should criticize grieving parents who have lost a son in combat. Capt. Khan was an American hero.

@ChadPergram: On Kahn, McCain says GOP nomination for Trump "is not accompanied by unfettered license to defame those who are the best among us"

@sahilkapur: CBS poll post-Dem convention Clinton 46% (+4) Trump 39% (-3)

@CNNPolitics: John Dickerson tells the #AxeFiles that Hillary Clinton is "not a very good campaigner" http://cnn.it/2afp1Ri 

@realDonaldTrump: When I said in an interview that Putin is "not going into Ukraine, you can mark it down," I am saying if I am President. Already in Crimea!
