Donald Trump tells non-Christians to identify themselves during a rally, asks audience; 'Should we keep them?'

Fresh from the debate stage on Monday night, Donald Trump hit the campaign trail again to raise support for his bid to become president.

On Wednesday, the Republican nominee was in Iowa where he was receiving the endorsement of a Christian Conservative group.

During the speech he asked members of the group to raise their hands if they were Christian Conservatives, to which he received a big cheer from the audience.
