After saying Donald Trump is “unfit” to succeed him as president, Barack Obama asked prominent Republicans “if you are repeatedly having to say in very strong terms that what he has said is unacceptable, why are you still endorsing him?”

Speaker of the House Paul Ryan, Senate Minority Leader Mitch McConnell and Sen. John McCain among other Republican icons have denounced Trump’s reaction to criticism leveled by the Gold Star parents of an American Muslim soldier who was killed while protecting fellow soldiers and civilians in Iraq.

Khizr Khan, with his wife at his side, addressed the Democratic National Convention last Thursday, saying “if it was up to Donald Trump, he never would have been in America.”

Trump’s tweets and remarks in an interview afterwards has consumed the political atmosphere for five days now. On Monday, Trump said U.S. Army Capt. Humayun Khan would not have been killed 12 years ago if he were president then because he wouldn’t have gone to war with Iraq back then.

When asked whether anything useful will come out of this feud with Trump, Khan told VOA “It really, really has come out that a significant larger number of Republicans are asking him to tone down, change those derogatory remarks about minorities, not only just Muslims but other minorities.”

The political fallout from all this is still being calculated.
