DUBAI - Saudi business magnate Prince Alwaleed bin Talal congratulated Donald Trump on his US presidential victory, almost a year after the two clashed bitterly on Twitter. 'President elect @realDonaldTrump whatever the past differences, America has spoken, congratulations & best wishes for your presidency,' the prince wrote on his twitter page. In December 2015 Bin Talal had called Trump a 'disgrace' and demanded he withdraw from the election after the property developer's pledge to ban Muslims entry into the US raised hackles in the Middle East. The next day, Trump issued a withering riposte: 'Dopey Prince @Alwaleed_Talal wants to control our US politicians with daddy's money. Can't do it when I get elected.'
