Miami ? The two brothers who once ran the world’s largest drug trafficking organization said the words Tuesday U.S. prosecutors had waited more than a decade to hear.

The aging drug kingpins pleaded guilty in Miami federal court to smuggling more than 200 tons of cocaine into the United States. They agreed to turn over companies, bank accounts and other assets connected to the drug trade worth more than $2 billion.

Now, Gilberto and Miguel Rodriguez-Orejuela, who turned cocaine running into a sophisticated, multibillion-dollar business as leaders of the notorious Cali Cartel, will spend 30 years in prison.
