In December 2015 Saudi Prince Alwaleed bin Talal slammed Donald Trump for proposing a ban on Muslim immigrants in the US until the government could alleviate security concerns.

Prince Alwaleed called Donald Trump a "disgrace" for his popular plan.

.@realDonaldTrump You are a disgrace not only to the GOP but to all America. Withdraw from the U.S presidential race as you will never win.

Donald Trump responded to attacks.

"@Michael2014abc: @Alwaleed_Talal @realDonaldTrump Has your country, Saudi Arabia, taken ANY of the Syrian refugees? If not, why not?"

Trump was right.
Saudi Arabia has banned Syrian immigrants from its country due to security concerns.
