He added that too many people have opposed Trump's travel ban, and made it too taboo to discuss.

"It makes them look stupid," Cain said of the terrorist attack.

"We can do better vetting and we can know who's here," he said.

British authorities on Tuesday identified the suicide bomber who struck at a Manchester Ariana Grande concert, hours after ISIS claimed responsibility for the attack.

Salman Abedi, 22, was identified as the man who detonated the improvised explosive device, killing 22 people and injuring 59.

The Telegraph reported Tuesday that Abedi was born in Manchester and that his parents had fled Libya as refugees.
