"NATO Allies are quickly moving to invest more in defense. Big increases announced and others to follow," he wrote on social media after a telephone call with the president, where he said: "The US and NATO are getting stronger."

"On Ukraine, Allies are preparing to contribute billions more in aid and security guarantees," he added.
