Jason D. Greenblatt currently serves as executive vice president and chief legal officer at the Trump Organization. During Trump's campaign, he advised the then-candidate on Israel and defended his boss against charges of anti-Semitism among his supporters.
Trump praised Greenblatt in a statement as one of his "closest and most trusted advisors" with "a history of negotiating substantial, complex transactions on my behalf, as well as the expertise to bring parties together and build consensus on difficult and sensitive topics."
Greenblatt will work on international negotiations "of all types" and trade deals, according to a press release from Trump's transition team. He is expected to work primarily on the Israel-Palestine peace process and the United States' relationship with Cuba, according to a CNN report published Friday, which cited an anonymous source familiar with his appointment.
