President Trump held a second, previously undisclosed meeting with Russian President Vladimir Putin during the G20 summit in Germany earlier this month. On Tuesday, the White House acknowledged the meeting, saying there was nothing unusual about it. But world leaders who witnessed the discussion called it highly unusual for Trump to single out an adversary while snubbing U.S. allies. Trump reportedly spoke for about an hour with Putin over dinner during their second face-to-face talk on July 7, relying on a Russian government translator because President Trump’s interpreter did not speak Russian. The conversation took place out of earshot of nearby observers, and there’s no sign the U.S. recorded a transcript of the conversation.
