Jewish-American billionaire Sheldon Adelson and his wife Miriam donated 13 million dollars to Birthright-Taglit, it was announced on Tuesday.
The couple's gift to the organization, which brings young Jewish adults on free trips to Israel, came in addition to the 20 million dollars they already gave it earlier this year.
Since its founding in 2000, Birthright has brought over 300,000 young adults to Israel from 59 countries.
