Donald Trump lashes back at 'dopey' Prince Alwaleed

Things were said — or, rather, tweeted. Feelings were hurt.

You could say US Republican and presidential hopeful Donald Trump started it when he said on Monday that America should ban Muslims from entering the country.

But then yesterday, Saudi billionaire Prince Alwaleed bin Talal called the US tycoon a "disgrace," not just to the GOP but to "all America."  

Trump's initial remarks came after a Muslim couple shot and killed 14 people in San Bernadino, Calif., on Dec. 2. In response, Trump urged a "total and complete shutdown of Muslims entering the United States until our country's representatives can figure out what is going on."

"We have no choice," Trump said, saying Islamist radicals want to kill Americans.

Of course, we do have a choice and Trump meant that statement to be provocative.

But that was before someone who is even richer than Trump (indeed, the richest Arab, according to Forbes) issued a public call for his withdrawal from the race. 

Trump's response: 

Take that, Alwaleed. He just called you "dopey." Give a shout when you recover.

Netizens were quick to point out the root of the issue.

It's true. Trump isn't the self-made man he purports to be. Rather, he built his own career on the back of his father's.

When Trump inherited a 20 percent share of his father's real estate empire in the 1970s, it was worth $200 million, reports the National Journal — and actually he could be even richer if he'd just invested wisely at the time, but whatever.
