The US had an office in Jerusalem dealing with Palestinians that Trump closed down. Biden and Blinken began to reopen it but the Israeli government have refused permission for the US to reopen it.
This is following Israel's throwing Palestinians out of their homes in East Jerusalem back in May and replacing them with settlers, which was followed by a mass bombing of the Gaza strip by Israel, including the building in which the Associated Press had its office, a building Israel said it purposely targeted.
This amidst settlement of Palestine's West Bank by Israel which is opposed by multiple UN resolutions supported by an overwhelming majority of nations.
