Trump's Special Representative for International Negotiations Jason Greenblatt claims Palestinians were invited to the Warsaw conference, in response to a think tank analyst who declared otherwise. Dear Martin- sorry but sources have misinformed you. The US did invite the Palestinians to join the conference and would have welcomed them there. They declined. https://t.co/O7jfMekvdG — Jason D. Greenblatt (@jdgreenblatt45) February 13, 2019 'The US did invite the Palestinians to join the conference and would have welcomed them there. They declined,' Greenblatt tweeted in reply to Martin Indyk, a fellow at the Council on Foreign Relations. The conference – officially called the Ministerial to Promote a Future of Peace and Security in the Middle East – will include representatives from at least 10 Arab states.
