New York, May 16 (RHC)-- U.S. Republican mega-donor and hard-line Zionist Sheldon Adelson will be contributing more than ever to help presumptive GOP presidential nominee Donald Trump get elected in November.

Adelson told Donald Trump during a private meeting last week that he was willing to spend $100 million for his presidential campaign, two Republicans with direct knowledge of the casino mogul’s commitment, told the New York Times. The report was published on Friday.

Adelson has decided to significantly scale back on his donations to the congressional Republicans to boost Trump’s chances of being elected, the report said.

The two men met at a hotel in New York and Adelson formally endorsed Trump.  During the meeting, Trump reportedly stressed that he is committed to the security of Israel.  Adelson, who together with his wife spent nearly $100 million in the 2012 presidential campaign cycle, is known to be a major supporter of Israel and its Prime Minister Benjamin Netanyahu.

Adelson had previously voiced support for Trump, but in a Washington Post article, he “strongly encourage[d]” those still on the fence about the divisive billionaire to do likewise.”

The multi-billionaire wrote that Trump “exemplifies the American spirit of determination, commitment to cause and business stewardship.”  Adelson, the CEO of the Las Vegas Sands casino group, was listed by Forbes in June 2015 as having a fortune of $28 billion, making him the 18th richest person in the world.

He is a major contributor to Republican Party candidates, which has resulted in his gaining significant influence within the party.  Adelson, a Zionist Jew, has said his most important issue when considering which candidates to support in U.S. elections is “the safety of Israel.”
