At the White House Correspondents' dinner, Joe Biden called for releasing wrongly detained Americans abroad and stressed the importance of journalism. "The free press is a pillar, maybe the pillar, of a free society, not the enemy,” Biden said in his speech. This year, the event took place about a month after a Wall Street Journal Moscow correspondent Evan Gershkovich was arrested in Russia and charged with spying, despite strong denials from his employer and the U.S. government. “We're working every day to secure his release,” Biden said. 📸: @apnews, @afpphoto via @GettyImages, Megan Smith/USA TODAY
