CHICAGO -- Donald Trump is standing by his proposal to ban Muslims from entering the United States.
The republican presidential candidate said the ban is warranted because the U.S. is essentially at war with Muslim extremists.
He pointed to recent deadly attacks in Paris and San Bernardino, California.
He said, "we are now at war" and "we have a president who doesn't want to say that.''
Some Muslims in Chicago say they are praying for Trump, despite his controversial remarks.
