Casino mogul and Republican mega-donor Sheldon Adelson, who has failed to come through with a pledge for up to $100 million in support for Donald Trump, has urged the presidential candidate show a measure of humility in his campaign, The New York Times said on Sunday.
Adelson, 83, reportedly met Trump last week in New York, where he conveyed his unhappiness with Trump's conduct.
The private meeting took place last Wednesday at New York's St. Regis hotel, five Republicans briefed on the conversation said, according to the Times report.
The following day Trump offered a general apology during a speech in Charlotte, North Carolina, saying that he regretted "saying the wrong thing." The Times said it was "unclear if it would be enough for him (Adelson) to fulfill" his campaign pledge.
Adelson's advisers told the Times Adelson was miffed by Trump's conduct following the Democratic Convention, a time at which the Republican candidate was under fire for ridiculing the parents of a Muslim-American soldier who was killed in Iraq.
Trump particularly needs Adelson's contributions to make up for a refusal of other donors to help support his campaign.
The Guardian Newspaper has suggested there were additional strains between Adelson and Trump.
In a report at the weekend the British daily said the mega-donor had pushed Trump to visit Israel and to pick Newt Gingrich as his running mate, but then Trump opted out of the visit and chose Mike Pence instead.
According to previous reports, Adelson has hinted he was willing to spend up to $100 million on the presidential race, but none of that money was given to any of Trump's Super PACs.
The Guardian also noted that several other key Republican donors, among them the Koch brothers, were shying away from the presidential race, opting instead to focus on saving Republican seats in Congress.
