Khizr Khan Challenges Donald Trump to Take Citizenship Test

The war of words between Republican presidential candidate Donald Trump and Gold Star parent Khizr Khan shows no signs of slowing down.

It all began at last month’s Democratic National Convention when Kahn and his wife, who lost their war hero son in combat, scathingly denounced Trump in a speech punctuated by Khan offering to lend the candidate his copy of the U.S. Constitution.

The barbs have continued from both sides since. Khan spoke out again yesterday in response to a Trump speech where the nominee said that if elected he’d institute a ideological test as part of U.S. immigration procedures to “screen out any who have hostile attitudes toward our country or its principles.”

Khan, who became a citizen after coming to the U.S. in 1980, openly challenged Trump, saying in an email to the Huffington Post:

“This is my country too. We must make it safe ― as Muslim Americans it is our obligation to keep our country safe. We reject all violence. We support better immigration policies. We stand as a testament to assimilation and being part of patriotic America as anyone else.”

From there, Khan challenged Trump to take the U.S. citizenship test. “I challenge Trump to take the naturalization test with me any day. His is demagoguery and pandering for vote. A divider like Trump can never be the steward of this country.”

While he’s tried to brush it off, the on-going feud with the Khans has been bad news for the Trump campaign. A recent survey found that a majority of Republicans have disapproved of how the candidate has handled the situation with the Khan family.
