The White House said on Friday that the proposal put forward by Hamas regarding a ceasefire agreement in Gaza in order to release prisoners is certainly within the limits of what is possible, expressing cautious optimism.

John Kirby, spokesman for the White House National Security Council, said that the proposal “certainly falls within the broad outlines of the agreement that we have been working on now for several months.”

"We're cautiously optimistic that things are moving in the right direction, but that doesn't mean it's done," Kirby told reporters.
