The Trump administration on Monday closed down the Palestine Liberation Organization’s office in Washington over concerns with the delegation’s attitude toward a U.S.-led peace process with Israel.

“The PLO has not taken steps to advance the start of direct and meaningful negotiations with Israel,” State Department spokeswoman Heather Nauert said in a written statement. “To the contrary, PLO leadership has condemned a U.S. peace plan they have not yet seen and refused to engage with the U.S. government with respect to peace efforts and otherwise.”
