The Brazilian president鈥檚 strong support of Venezuela鈥檚 authoritarian leader has marred the unity at a South American summit that Brazil convened in hopes of reviving a bloc of the region鈥檚 12 politically polarized countries.

Brazilian voters are being bombarded by online misinformation, less than a week before they pick their next leader. Baseless rumors are whipping through social media in Latin America鈥檚 largest democracy, roiling Brazilian politics much as U.S. politics has been roiled.
