ST. LOUIS (CBSNewYork) — Hillary Clinton’s foreign policy spokesperson slammed Donald Trump when talking about a Bronze Star recipient who lost his life during the Iraq War.

“First of all, Capt. [Humayun] Khan is an American hero and if I were president at that time, he would be alive today,” Trump said during the presidential debate Sunday night.

Khan posthumously received a Bronze Star and a Purple Heart after he was killed by a suicide bomber in Iraq in 2004. His parents, Khizr and Ghazala Khan, gave an emotional speech at the DNC over the summer.

Trump said he was “viciously attacked” by the family at the time, and also questioned if their Muslim religion stopped Ghazala Khan from speaking at the DNC. She said in a later interview that she was too emotional at the time to speak.

On Twitter, Jesse Lehrich, Clinton’s foreign policy spokesperson, said, “Hey, (at)realDonaldTrump – regarding your claim that Captain Khan would be alive if you were president: go f*** yourself.”

Lehrich later apologized for the tweet.

“I want to apologize for the clearly inappropriate nature and language of this personal tweet. Sorry all,” Lehrich said.
