Donald Trump was speaking at an event in Iowa, complaining that America was not allowed to waterboard terrorists, when Khizr Khan and his wife walked up to the microphone at the Democratic National Convention in Philadelphia.



Khan's son Humayun Khan was a captain in the U.S. Army. When a vehicle packed with explosives approached his compound in Iraq in 2004, he instructed his men to seek cover as he approached it. It exploded, killing Khan instantly. He was awarded the Bronze Star posthumously.



"We are honored to stand here as the parents of Capt. Humayun Khan," the elder Khan said, "and as patriotic American Muslims with undivided loyalty to our country." He spoke of his son's dreams of becoming a military lawyer and how Hillary Clinton had referred to his son as "the best of America."



Then he focused his attention on Trump.
