NATO Secretary General Mark Rutte is set to meet President Donald Trump this week on the heels of the U.S. leader announcing plans to sell NATO allies weaponry that it can then pass on to Ukraine.

President Donald Trump told NBC he struck a deal with NATO on Thursday for the US to send weapons to Ukraine through the alliance, and that NATO will pay for those weapons “a hundred percent.”

United States military and NATO officials are discussing a possible plan that could be unveiled in the coming days that would provide Ukraine with much-needed aerial defense weapons, including Patriot systems, by funneling U.S. weapons through the European alliance, officials said.
