President-elect Donald Trump’s team is discussing plans to designate Mexican cartels as terrorist organizations, according to three sources familiar with the discussions, bringing back an idea that failed to come to fruition during his first term in office.

President Donald Trump has signed an executive order saying the United States will designate drug cartels as foreign terrorist organizations, a move that could push a militarized agenda for the border and Latin America.

Cartels have set off car bombs and beheaded victims. But designating them as terrorist groups could have unforeseen consequences.
