Mexican authorities continued to contradict themselves over the role of two CIA agents in a counternarcotics operation in northern Mexico and the extent to which Mexico’s federal government was aware of the U.S. involvement in the incident, which has started to ignite tensions with the White House. The officials were returning from destroying a drug lab in northern Mexico. Two Mexican investigators also died in the crash. Sheinbaum emphasized that U.S. agents shouldn't operate in Mexico without consent. She ruled out a new strategy by the U.S. to deploy agents without Mexico’s knowledge and highlighted existing communication with the U.S. State Department.
