Trump lashes out at allies ahead of G7 summit
At the G7 summit Friday, President Trump is expecting tough talks with six U.S. allies: Canada, France, Britain, Germany, Italy and Japan. Relations are tense after Mr. Trump put new tariffs on imported steel and aluminum from the European Union, Mexico and Canada. Those nations threaten new tariffs of their own on U.S. goods.
