President Donald Trump said Monday that the U.S. would be sending weapons to Ukraine and they would be paid for by the North Atlantic Treaty Organization (NATO).

Trump made the announcement with NATO Secretary General Mark Rutte during a meeting at the Oval Office, according to Politico.

“We’ve made a deal today where we are going to be sending them weapons, and they’re going to be paying for them,” Trump stated. “They feel strongly about it, and we feel strongly about it, too. But we’re in it for a lot of money, and we don’t want to do it anymore.”

During the meeting, Trump also warned that the U.S. would issue tariffs on Russia if a deal to end the war was not brokered in 50 days.

The administration restarted its shipment of some defense weapons to Ukraine earlier this month, days after the Department of Defense ordered a pause on delivering some air defense missiles and munitions because of concerns about U.S. stockpiles being depleted.

Earlier this month, Ukrainian President Volodymyr Zelensky said he had a very productive conversation with Trump regarding the Russia-Ukraine war. 

Trump said he was "very unhappy" after his recent conversation with Russian President Vladimir Putin. He also said Putin does not want to work toward a ceasefire deal.
