Did Trump go too far?

Donald Trump's criticism about the Muslim parents of a slain American soldier has generated -- once again -- a backlash within his own party.

Just 100 days from the election, Trump has responded in his standard fashion -- dig in, claim he's being treated unfairly and attack back.

But the swift condemnation of Trump's response raises questions about whether this controversy is different from the ones that came before it.

It certainly isn't going away - Khizr and Ghazala Khan appeared for a lengthy joint interview on CNN's "New Day" on Monday where Khizr accused Trump of "ignorance and arrogance."

Khan also said he's received an outpouring of support for speaking out against the GOP presidential candidate, including from many Republicans. And he warned that Trump's attacks on Muslims are boosting terror recruitment. Khan said it is good Muslims who are the ones who can help stop terror and make American safer.

"We are the solution to terrorism," Khan said on CNN Monday.

Trump tweeted during the interview that the issue was not the Khans, it was stopping the spread of radical Islamic terrorism.

The White House also weighed in with an implicit rebuke of Trump, saying that Gold Star families deserve only "honor and gratitude" for their loved ones' service.

Speaking aboard Air Force One, spokesman Eric Schultz wouldn't provide a specific response to Trump's comments about the Khan family. But he said honoring Gold Star families should rise "above politics."

"Families who make the ultimate sacrifice for this country's freedom and this country's safety deserve nothing but our country's honor and gratitude and deepest respect," Schultz said.

Also on Monday, Hillary Clinton's runningmate, Tim Kaine, said, "Is it OK to speak in a disrespectful way about the military, about a Gold Star mom and dad for God's sake, about people with disabilities, or saying offensive things about women, or trash people who are Latinos or immigrants more generally?"

"We're either going to build a community that is a more perfect union, that is a community of respect or we're going to decide to do what has been done throughout American history but never to our advantage," Kaine said during a campaign stop in Richmond, Virginia.

This time, attacks from the Republican presidential nominee on the parents of a soldier who died defending America have put new pressure on GOP leaders to decide whether they will continue to stand by him. Already, the party's leaders in the House and the Senate have distanced themselves from Trump's remarks, and other Republican figures are attacking their nominee forcefully.

Sen. John McCain issue a very personal statement Monday blasting Trump's comments about the Khans and paying homage to their son Humayun's sacrifice. McCain noted that his son also served in the Iraq War and the McCains have been serving in the US military for hundreds of years.

"It is time for Donald Trump to set the example for our country and the future of the Republican Party," McCain said. "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.

"Lastly, I'd like to say to Mr. and Mrs. Khan: thank you for immigrating to America. We're a better country because of you. And you are certainly right; your son was the best of America, and the memory of his sacrifice will make us a better nation -- and he will never be forgotten."

Sen. Lindsey Graham, R-South Carolina, said in a statement: "This is going to a place where we've never gone before, to push back against the families of the fallen. There used to be some things that were sacred in American politics -- that you don't do -- like criticizing the parents of a fallen soldier even if they criticize you."
