Remembering Talal's tweet to Trump in Dec, 2015:
"@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"
Trump replied the next day:
"Dopey Prince @Alwaleed_Talal wants to control our U.S. politicians with daddy's money. Can't do it when I get elected."
Apparently Trump was right :-)
Trump's advisor and son-in-law Jared Kushner took an un-announced visit to Saudi last week. And these arrests were made the next day he left.
