Following through on threats, the Trump administration has designated Brazil’s two largest drug gangs as terrorist groups.

The United States plans to designate Brazil’s two biggest drug gangs as terrorist groups on Thursday, after months of aggressive lobbying by the sons of the jailed former president, Jair Bolsonaro, a close ally of President Trump’s.

The move comes just days after two of Mr. Bolsonaro’s sons, one of whom plans to run for president later this year, visited Mr. Trump at the White House.
