GOP rapped for raising Sharia law.

The Republican National Committee (RNC) is taking an online "Listening to America" survey that asks Americans, "Are you concerned by the potential spread of Sharia Law?"

The Council on American-Islamic Relations (CAIR) has written the party asking it to remove the question.

The CAIR letter says, "Just as it would be widely condemned as extremely inappropriate and indecent for the RNC to ask Americans if they are concerned about the potential spread of Catholic cannon law and Jewish Halacha, posing questions about the religious teachings practiced by American Muslims should be likewise condemned by the Republican Party.

"The Republican Party should not allow its resources to be hijacked by those who would seek to use its stature in American society to fuel the rise of un-American and anti-Muslim bigotry in our country," CAIR wrote.

CAIR said the survey question also recently appeared in a Donald J. Trump campaign email.
