Excerpt

SUMMARY:  In Japan, President Trump warned Russian President Vladimir Putin and his staff not to meddle in the 2020 election, but he did so with a grin.  Although G-20 summits have historically been calm conferences, President Trump has made them less predictable.  He will finish his trip to Osaka with a pivotal meeting with Chinese President Xi Jinping.  Nick Schifrin reports.
