SOURCE - "After his much-publicized two-and-a-quarter-hour meeting early this month with Russian President Vladimir Putin at the Group of 20 summit in Germany, President Trump chatted informally with the Russian leader for up to an additional hour later the same day.
The second meeting, undisclosed at the time, took place at a dinner for G-20 leaders, a senior administration official said. At some point during the meal, Trump left his own seat to occupy a chair next to Putin. Trump approached alone, and Putin was attended only by his official interpreter."
