Herman Cain, 2012 US Republican presidential candidate, says Donald Trump is qualified to be commander-in-chief. 

Cain, who sat down with Mehdi Hasan at the 2016 Republican National Convention, says the US Republican nominee is a "listener, leader, a fighter and a winner".

On whether Trump, who in the past admitted he didn't know the difference between Hamas and Hezbollah, is qualified to run the country, Cain says he "doesn't need to know" because "a leader learns as he goes ... a leader asks the right questions."
