As President Trump meets with Russian President Putin in Helsinki, we host a debate on U.S.-Russia relations. Joe Cirincione, the president of Ploughshares Fund, calls the summit “a danger to America and to the West.” In Rio de Janeiro, Brazil, Glenn Greenwald joins us, one of the founding editors of The Intercept. Greenwald calls the Trump-Putin meeting “excellent” and says it’s “lunacy” to paint alleged Russian meddling in U.S. elections as the biggest threat to U.S. democracy.
