Donald Trump has gone too far with his "unprecedented" attack on the family of a US Muslim solider killed on duty in Iraq in 2004, a spokeswoman for the Republicans Overseas movement has told talkRADIO.
The Republican Party's US presidential candidate caused shockwaves in the United States with comments aimed at Khizr and Ghazala Khan, whose son Humayan was killed by a car bomb while serving as a US Army captain.
Trump's outbust came after Mr Khan, with his wife alongside him, spoke at the Democratic National Convention, saying "if it had been up to Donald Trump, Humayun would never have been in America" and that the billioniare politician had "sacrificed nothing and no-one".
Speaking on the ABC's This Week TV show, Trump disputed the Khans' statement and said: "[Ghazala Khan] had nothing to say… maybe she wasn't allowed to have anything to say. You tell me."
Kate Andrews, from Republicans Overseas, was taken aback by her party's candidate.
"It is just baffling to me," she told Julia Hartley-Brewer. "In a presidential election we have a candidate attacking the family of a fallen American solider, it is so unprecedented.
"If you are going to be the next president of the United States, you must be above the fray. You will probably be the most criticised person in the world.
"I'm really saddened by his remarks and I cannot believe he has gone this far."
