(FOX 11) - Saudi billionaire Prince Alwaleed bin Talal called Donald Trump a "disgrace" via Twitter on Friday after his call to ban Muslims from entering the country.
"You are a disgrace not only to the GOP but to all America," the chairman of Kingdom Holding Co. posted on Twitter. "Withdraw from the U.S presidential race as you will never win."
Prince Alwaleed is a nephew of Saudi Arabia's King Salman and has made investments in a number of international companies, including Twitter, Citigroup and AOL, Apple and 21st Century FOX, the parent company of FOX News.
He was listed as the 34th richest man in the world by Forbes.
The Republican front-runner responded within hours, also on Twitter, referring to him as "dopey."
"Dopey Prince @Alwaleed_Talal wants to control our U.S. politicians with daddy's money. Can't do it when I get elected."
