Dakota Meyer, the Medal of Honor winner who recently married Sarah Palin’s daughter, has told Republican presidential candidate Donald Trump to man up and apologize to the family of slain US Army Capt. Humayun Khan. Palin is a strong Trump supporter.

Meyer, the second youngest living person to receive the military’s highest honor, delivered a blunt message to Trump.

“If @realDonaldTrump wants to be the Commander in Chief, he needs to act like one,’ Dakota wrote on Twitter. “And that can’t start until he apologizes to the Khans.”

Meyer added his voice to dozens of fellow veterans and Republican members of Congress–not to mention Democratic candidate Hillary Clinton. Trump has faced near universal condemnation for his remarks about the family.

The former Marine, 28, married to Bristol Palin, the daughter of 2008 Republican vice-presidential candidate Sarah Palin, after fathering her child last year. The couple briefly broke up before reuniting and marrying.

Meyer supported Texas senator Ted Cruz in the Republican primary, while Sarah Palin backed Trump.

Khan’s father, Khizr, spoke at the Democratic National Convention with his wife Ghazala at his side. He criticized Trump’s blanket call to ban all Muslims from entering the United States as potential terror threats.

His speech was the emotional high-point of the convention. Khizr challenged Trump to demonstrate his knowledge of the U.S. Constitution and the loyalty and sacrifice of his family.

In the most emotional moment of the speech, Khizr said to Trump: “You have sacrificed nothing and no one.”

Trump avoided military service during the Vietnam war, by claiming he suffered from “bone spurs” on his feet.

Humayun Khan, 27, was killed in Iraq in 2004 by a suicide bomber while trying to protect his men. He was posthumously awarded the Bronze Star and Purple Heart.

When asked to respond to Khizr’s remarks, Trump called the speech a “vicious” attack and questioned why Ghazala didn’t speak, implying that she remained silent–and subordinate–for religious reasons.

Ghazala responded in an emotional Washington Post column. She said she was still too emotional over her son’s death to speak.

Trump, who has withstood numerous challenges to his character and business dealings, has been unable to shake this controversy. It’s still roiling and helping to drive down his poll numbers.

So far, he has still refused to apologize, although he’s said he honors the son for his sacrifice.

To Meyer and others, that’s not enough.

Dakota Meyer, the author of Into the Fire, received the Medal of Honor for his actions in Afghanistan in 2009.
