A former comrade-in-arms of US Army Capt. Humayun Khan, whose Muslim parents have been engaged in a bitter feud with Donald Trump, has joined a growing chorus of people calling the GOP nominee unfit for the Oval Office.

Miles Smith, 37, a Texas-born Australian who served in the same unit as Khan in Iraq – and heard the suicide blast that killed him – called Trump a threat to national security. “He (Trump) wants this to go away,” Smith told The West Australian. “I’m going to do what I can here to kick the ball forward, continue their (the Khans’) message and stand up for them. They are better citizens than he is.”

Trump has come under fire for his reaction to a powerful speech made by Khan’s father, Khizr, during last month’s Democratic National Convention, when he denounced the nominee’s calls to ban Muslims from entering the US.(nypost.com)…[+]
