Senior U.S. drug official praises cooperation with Mexico, a 'law enforcement wall'

A top U.S. drug official made a strong case Thursday for continued cooperation with Mexico on fighting drug-trafficking, saying successful law enforcement already has created a virtual wall.

In a subtle dig at the Trump administration, William Brownfield, the State department's senior diplomat involved in drug policy, said that despite a crisis drug epidemic, the United States and Mexico were in a better position than ever to combat it.

"In a sense, we have developed a law enforcement cooperative wall at this point without actually having the physical construction of a wall," Brownfield said.
