Mexico says U.S. Homeland Security Secretary John Kelly has visited one of the country’s most restive states and watched troops destroy opium-poppy fields.

Kelly arrived to Mexico on Wednesday and met with President Enrique Peña Nieto before the Mexican leader departed for France ahead of the Group of 20 summit in Germany.

Kelly, along with CIA Director Mike Pompeo, met with Peña Nieto to discuss approaches to transnational crime, regional security, and economic cooperation.

Arkansas Republican Sen. Tom Cotton, who sits on the Senate select committee on intelligence, was also a part of the meeting.
