It is unclear which former Trump official the question is referring to. However, it is important to recognize that the US does not have any authority to deport Palestinians. Palestinians living in the West Bank are subject to the jurisdiction of the Israeli government, while those living in the Gaza Strip are subject to the jurisdiction of the Palestinian Authority. It is up to the government in those respective areas to determine who can enter or depart. Therefore, no US official, including a former Trump official, would have the authority to deport Palestinians.
