Republican mega-donor Sheldon Adelson told Donald Trump in a private meeting that the Republican presidential candidate must demonstrate a measure of humility. Adelson, a billionaire casino magnate, also told Trump in the meeting last week in Adelson’s suite at the St. Regis Hotel in New York that he was committed to his presidential campaign. Adelson’s wife, Miriam, also a large donor to the Republican Party, reportedly was at the meeting with Trump on Wednesday. Neither Adelson has contributed to Trump’s campaign, to groups supporting him or to the Republican National Committee since they pledged to support him during a private meeting in May at the same hotel, the Times reported.
