Billionaire-businessman Donald Trump officially became the US Republican presidential nominee earlier this week at the Republican National Convention (RNC).  

The opening day of the convention, however, was met with heightened controversy when a group of delegates known as "Never Trumpers" failed to block the Trump nomination, while on Wednesday night, Trump's former opponent, Ted Cruz, refused to endorse his fellow Republican.

So, as controversy continues to surround Trump's candidacy and the Republican Party, can the businessman and reality star win the US presidency?

In a special UpFront, from the RNC, we speak to one of Trump's top advisers, potential defense secretary Michael Flynn, about why he supports the candidate.

Mehdi Hasan asks "Never Trump" delegate Dane Waters why, as a Republican, he wanted to block the nomination. We also speak to 2012 Republican presidential candidate Herman Cain about why he believes Trump is qualified to be commander-in-chief.

And in the Reality Check, Mehdi Hasan takes a look at what the rest of the world thinks about a potential Trump presidency.
