President Donald Trump aimed insults at Emmanuel Macron on the first day of a two-day NATO conference. Trump is angry at the French president for recently saying NATO was experiencing “brain death” as a result of diminished U.S. leadership under Trump. Face to face with Trump, Macron stood by his comments and also expressed his frustration that the president withdrew U.S. troops from Syria. Trump also commented Tuesday on impeachment, assailing Democrats at home as “unpatriotic” for holding a hearing while he is abroad at the conference.
