Donald Trump denies being 'a bigot' after Muslim ban remarks

Donald Trump's anti-Muslim rhetoric undermines US national security by boosting the Islamic State (IS) group, the Pentagon has warned.

The leading Republican presidential candidate has said Muslims should be banned from entering the US, in the wake of the deadly California attacks.

Speaking to Barbara Walters on ABC World News Tonight, Donald Trump denied he was a bigot.

''Somebody in this country has to say what's right,'' he said.
