Colombian President Gustavo Petro is under investigation by the U.S. Department of Justice for his alleged drug trafficking ties. The investigations focus on whether Petro's presidential campaign solicited donations from drug traffickers and held meetings with them. Petro, a leftist and former member of Colombia's M-19 guerrilla group, has previously criticized President Donald Trump for ordering lethal strikes on boats in the Caribbean identified as participating in drug trafficking. It is unclear whether these investigations will result in criminal charges.
