Khizr Khan stars in emotional Clinton campaign ad

Nearly four months after he first spoke out against Donald Trump at the Democratic National Convention, Khizr Khan is taking on the GOP nominee yet again.

In a new ad released by Hillary Clinton’s campaign Friday, the Pakistani-born lawyer and Gold Star father describes the 2004 suicide bombing that killed his son, Army Capt. Humayun Khan, who was serving in Iraq in 2004.

“My son moved forward to stop the bomber,” Khan says in the commercial. “He saved everyone in his unit.”

The video cuts from shots of Khan looking somberly through photographs of his son to a clip of Trump at a campaign rally and then back to Khan, comforting his wife, Ghazala, as they watch footage of their son’s burial at Arlington Cemetery on a small TV.

Audibly choking back tears, Khan’s voice quivers as he says, “I want to ask Mr. Trump, would my son have a place in your America?”

The question was a clear reference to Trump’s ardently anti-Muslim policy proposals, including his calls for a temporary ban on Muslim travel to the U.S., profiling of American Muslims and increased surveillance of mosques.

But it’s also the latest move in an ongoing feud between the Muslim-American Khan family and Trump, who lashed out after Khizr Khan spoke at the Democratic convention in Philadelphia. In his speech there, Khan questioned the Republican nominee’s understanding of the U.S. Constitution and accused him of having “sacrificed nothing” for his country.

In response, Trump suggested that Ghazala, who stood silently onstage next to her husband, might have actually been forbidden from speaking at the convention. (Ghazala clarified in a Washington Post op-ed that she’d actually been in too much pain to speak.)

Despite the expressed disapproval of prominent Republicans like Rep. John McCain and even one of his closest allies, New Jersey Gov. Chris Christie, Trump has continued to trade barbs with the Khans.

Trump made his latest attack earlier this month, when he suggested during the second presidential debate that, if he were president in 2004, Capt. Humayun Khan would still be alive today because “I would not have had our people in Iraq.”

In a recent interview with Yahoo Global News Anchor Katie Couric, Khizr Khan called Trump’s comments at the debate “disingenuous, self-serving,” and further proof of Trump’s “inability to lead this country.”

To suggest that their son would still be alive if Trump had been in charge “is the worst thing that you can say to a parent about their children,” Khan said, adding, “This what you never say to somebody who has lost their loved one.”

Khan’s appearance in the new Clinton ad came just days after Trump’s campaign released an emotional advertisement of its own featuring Laura Wilkerson, whose son was killed by an undocumented immigrant.
