Rallying at Columbus' Fort Hayes High School on Sunday, Hillary Clinton said Donald Trump repaid the "ultimate sacrifice" of a U.S. Army captain killed in Iraq with insults and degrading comments about Muslims, as the soldier's bereaved father pressured Republican Party leaders to distance themselves from the GOP presidential nominee.
Clinton's comments came after Trump refused to back down from his criticism of the Gold Star parents' remarks.
"Am I not allowed to respond?" Trump had tweeted. "Hillary voted for the Iraq war, not me!"
It was the latest bitter rhetorical volley between the defiant Republican candidate, Clinton and the family of a fallen soldier since the two parties concluded their conventions last week and the nation looked ahead to a close election this November.
Trump's stand has once again left Republican leaders facing demands to denounce their party nominee and overshadowed Clinton's campaign message with controversy.
"He is a black soul," said Khizr Khan, whose son Humayun received a Bronze Star and a Purple Heart after he was killed in Iraq in 2004. "And this is totally unfit for the leadership of this beautiful country."
Speaking on CNN's "State of the Union," he said, "It is majority leader's and speaker's moral, ethical obligation to not worry about the votes, but repudiate him, withdraw the support."
Likewise, Clinton told Republicans on Sunday: "This is a time to pick country over party."
In statements released Sunday, Senate Majority Leader Mitch McConnell and House Speaker Paul Ryan condemned any criticism of Muslim Americans who serve their country and rejected the idea of a Muslim travel ban - an idea proposed by Trump earlier in the campaign. But neither statement mentioned Trump by name or repudiated him.
McConnell praised Capt. Khan as an "American hero," while Ryan noted that many Muslim Americans have served "valiantly" in the U.S. military.
“Captain Khan was one such brave example. His sacrifice - and that of Khizr and Ghazala Khan - should always be honored. Period," Ryan said.
On a post-convention bus tour through Ohio and Pennsylvania, Clinton said Trump has a "total misunderstanding" of American values and has inflamed divisions in American society.
"I don't know where the boundaries are. I don't know where the bottom is," she told reporters during a campaign stop at a cheese barn in Ohio.
"I do tremble before those who would scapegoat other Americans," she told parishioners in a Cleveland church on Sunday morning. "That's just not how I was raised."
At last week's Democratic National Convention, Pakistan-born Khan told his son's story and questioned whether Trump had ever read the Constitution and said "you have sacrificed nothing."
During the speech, Khan's wife, Ghazala, stood quietly by his side.
"If you look at his wife, she was standing there. She had nothing to say. She probably, maybe she wasn't allowed to have anything to say," Trump said, in an interview with ABC's "This Week."
Ghazala Khan responded Sunday in an opinion piece published in The Washington Post, saying talking about her son's death 12 years ago is still hard for her. When her husband asked if she wanted to speak at the convention, she said she could not.
“When Donald Trump is talking about Islam, he is ignorant," she wrote.
At one point, Trump had disputed Khan's criticism that the billionaire businessman has "sacrificed nothing and no one" for his country.
"I've made a lot of sacrifices. I work very, very hard. I've created thousands and thousands of jobs, tens of thousands of jobs, built great structures," Trump said.
Trump, who had no campaign events scheduled this weekend, released a statement late Saturday night calling Humayun Khan "a hero" but disputing his father's characterization.
"While I feel deeply for the loss of his son, Mr. Khan who has never met me, has no right to stand in front of millions of people and claim I have never read the Constitution, (which is false) and say many other inaccurate things," said Trump.
Trump's rebuke was unusual in the world of politics where officials only speak well of families whose loved ones die in service to their country. When Cindy Sheehan, who lost her son in Iraq, staged prolonged protests on the war, then-President George W. Bush responded by saying that the nation grieves every death.
When asked about the mother of a State Department official killed in Benghazi, Libya, who blamed Hillary Clinton for her son's death, Clinton told "Fox News Sunday" that her "heart goes out" to the families and that she didn't "hold any ill feeling for someone" who has lost a child and recalls events differently.
Across the country, veterans and their families closely watched the political back-and-forth.
"It was inappropriate on both sides," said Mark Farner of Ocean Isle Beach, North Carolina, as he stood a few feet from the Vietnam Veterans Memorial in Washington. "For one to use it as it as the Democrats intended it to be used, and I don't think Trump handled it the way he should have on his end."
Farner had just made a rubbing of the name of his cousin, Calvin Wilson, who was killed in action in February 1967.
Romell Short of Washington, a U.S. Marine Corps veteran who deployed to Iraq and Afghanistan, said he has no problem with veterans' families being politically active and speaking about their experiences.
"America should know the suffering and the cost of war and part of that is the sacrifice of American troops and the sacrifice of American families," Short said.
But he cautioned that the views of families should be read separately from their family member who served.
