Law enforcement agencies have arrested more than 2,200 people in an investigation targeting Mexican drug trafficking organizations in the United States, the Justice Department announced Thursday.
The probe, called Project Deliverance, focused on the transportation networks that carry methamphetamine, cocaine, heroin and marijuana into the United States, with return trips of drug proceeds and weapons.
At a news conference Thursday, Attorney General Eric Holder said the extensive operation began nearly two years ago. He said federal agents targeting violent drug cartels have seized nearly 70 tons of marijuana and nearly 1,500 pounds of heroin. Authorities said some of the drugs were hidden inside buses that cross the Southwest border.
