Trump added that he is "sending Israel everything it needs to finish the job," and that "not a single Hamas member will be safe if you don’t do as I say.
"I have just met with your former Hostages whose lives you have destroyed," Trump added. "This is your last warning! For the leadership, now is the time to leave Gaza, while you still have a chance."
"Also, to the People of Gaza: A beautiful Future awaits, but not if you hold Hostages. If you do, you are DEAD! Make a SMART decision. RELEASE THE HOSTAGES NOW, OR THERE WILL BE HELL TO PAY LATER!"
Trump's post came hours after the White House was challenged by Fox News senior White House correspondent Peter Doocy on its decision to negotiate with the Palestinian terrorist group.
