Canada’s leader Mark Carney formally opens the G7 summit saying the meeting falls at “one of those turning points in history.”

Former US Ambassador to NATO Ivo Daalder reacts to President Trump’s comments at the G7 and talks with CNN’s Wolf Blitzer about the challenges leaders will face during the summit.
