A diplomatic rift is hindering cooperation between the United States and Brazil on jointly fighting organized crime, according to U.S. and Brazilian officials. The Trump administration is blocking visas for two Brazilian federal police agents assigned to posts in the United States, where they would work with U.S. Homeland Security Investigations to combat transnational crimes. In response, Brazil is blocking the visa of a U.S. law enforcement official meant for the country, creating a tit-for-tat Visa dispute that has disrupted decades of joint anti-crime collaboration.
