When Donald Trump said in the fall he would consider making Muslims in the United States carry special identification cards, Tayyib Rashid reached into his wallet and pulled out his military ID, then posted a picture of it online, adding:

“Hey @realDonaldTrump, I’m an American Muslim and I already carry a special ID badge. Where’s yours?”

Now, Rashid, who served five years in the Marine Corps infantry, deploying three times, has been outraged again by Trump. This time it is because of the Republican presidential nominee’s disparaging comments about Khizr and Ghazala Khan, the parents of an Army captain killed by a car bomb in Iraq in 2004, who criticized Trump’s proposed policies toward Muslims at the Democratic National Convention.

The episode “brought tears to my eyes,” Rashid said. “These are people who sacrificed their own child, their own blood.”
