Trump, Macron to meet after French president criticized NATO

French President Emmanuel Macron says he will meet with U.S. President Donald Trump ahead of the Dec. 3-4 NATO summit in London

The phone call comes after Macron claimed last week that a lack of U.S. leadership is causing the "brain death" of NATO and said the European Union must step up and start acting as a strategic world power.

Trump's preoccupation with defense spending has been a constant theme since he came to office in 2016 and is expected to feature at the Dec. 3-4 summit in London.
