On her radio show today, Sandy Rios of the American Family Association (AFA) questioned the patriotism of Khizr Khan, the father of U.S. Army Capt. Humayun Khan, who died while serving in Iraq. Khan gave a rousing speech at the Democratic National Convention yesterday, in which he criticized Donald Trump’s proposal to ban Muslims from entering the U.S.

Rios, who serves as the AFA’s director of governmental affairs, said that because of his Muslim faith, Khan may be lying to Americans about his true beliefs, arguing that “supporters of Islam and the Quran cannot embrace the Constitution” and that it’s Khan’s “responsibility” to publicly “condemn Islamists” to prove his allegiance to the country.

“From my perspective, it is the responsibility of Mr. Khan to distinguish himself from Islamists, from the Muslim Brotherhood whose treatise is to destroy us from within,” Rios said. “If he is a patriotic, loyal, American Muslim, then we want to hear that, that’s great, and we grieve with them over the death of their son. But do not disparage Americans or Donald Trump for having concerns about Muslims in our midst.”

She continued, “And if you are so concerned, Mr. Khan, if you’re an American first, then distinguish yourself and condemn Islamists, condemn the Muslim Brotherhood, then we will listen to you, and stop waving the Constitution. As far as I can tell, Islam, truly, supporters of Islam and the Quran, cannot embrace the Constitution. Now, if you have a different view, then explain that to us and then maybe we can be persuaded, but don’t shame America for having genuine and rightful concerns about Muslims in our midst when we have no idea who they are or what they really believe, and we’re not even sure about you, sir, because we know about taqiyya, which is the practice of lying to the infidel in order to advance the Muslim cause.

“So, I’m sorry, we’ll not be shamed. I’m sorry for the loss of their son and I hope he is a loyal American, but I think a loyal American Muslim would be more like Zuhdi Jasser, who is very clear about where he stands, who was very patriotic and loyal and totally distances himself from Islamism, so if that’s the case for this gentleman, then he should’ve said that on the platform rather than shaming us for having concerns about Muslim immigration.”
