Sheldon and Miriam Adelson are contributing an additional $5 million to Birthright Israel, which the organization says will move 2,000 applicants from waitlisted to traveling this winter.
The contribution announced Wednesday, a day after the Adelsons were honored in Washington by the group, doubles their contribution for this year to $10 million.
"In light of this announcement, Taglit-Birthright Israel is now sending letters to 2,000 North American young adults who had applied for a trip this winter but were waitlisted, informing them that they will now be able to go on the free, 10-day educational trip in the coming months thanks to the new funding," the group said. "Nearly 22,500 North Americans had registered for Taglit-Birthright Israel trips this winter and over 10,000 young adults had been waitlisted."
The Adelsons' foundation has given Birthright more than $100 million since 2007.
Adelson, a casino magnate, is a major giver to Jewish and conservative causes.
