An official US source on Thursday told Reuters that the White House talks regarding the application of sovereignty in Judea and Samaria concluded without a decision being made, as US President Donald Trump is still unsure of whether to support the move. US Ambassador to Israel David Friedman also attended the meeting. US Special Representative to the Middle East Avi Berkowitz will fly to Israel Thursday night, together with Ambassador Friedman, in order to continue the coordination ahead of the application of sovereignty. A senior White House official said: "The meetings this week were productive. Ambassador Friedman is returning to Israel tonight with Special Envoy Avi Berkowitz and Mapping Committee member Scott Leith for further meetings and analysis. There is yet no final decision on next steps for implementing the Trump plan." Earlier on Thursday, reports said that Mossad Chief Yossi Cohen visited Jordan , meeting with King Abdullah II to discuss Israel's intention to apply sovereignty. On Monday, leading Republican lawmakers sent a letter to Trump , expressing their support for Israel's right to apply sovereignty to Judea and Samaria. "As dedicated friends of the Jewish state, we reaffirm our steadfast commitment to the relationship between our two nations and Israel’s right to sovereignty and defensible borders," they wrote.
