Fearing Trump will cross border militarily to pursue cartels, Mexico moves to reform constitution

Sheinbaum made the remarks after the Trump administration designated six Mexican drug cartels as foreign terrorist organizations, stoking fears that President Donald Trump may be setting up the possibility for U.S. military action inside Mexico.

"The Mexican people will not accept under any circumstances interventions, interference or any other act from abroad that could be harmful to the integrity, independence and sovereignty of the nation," Sheinbaum said.

Mexico, which has long rejected such a move by the U.S. to designate cartels as foreign terrorist organizations, was not consulted about the decision, Sheinbaum said.

"What we want to make clear in the face of this designation is that we do not negotiate sovereignty," Sheinbaum said. "This cannot be an opportunity for the United States to invade our sovereignty."

Mexico has long demanded that the U.S. do more to prevent guns from being smuggled into Mexico from the U.S.
