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.

In a statement, NATO said NATO Secretary General Mark Rutte will be in Washington on Monday and Tuesday and meet with President Trump and key administration officials.

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.”
