Mexican authorities arrested former Chihuahua Attorney General Cesar Jauregui on Saturday on suspicion of treason. Prosecutors allege Jauregui allowed US agents to participate in an "irregular" raid on a suspected drug laboratory in April in the northern border state of Chihuahua without the authorization required under Mexican law. The US acknowledged in April that two employees of its embassy in Mexico City had died, with sources familiar with the matter identifying them as CIA officers involved in anti-narcotics efforts. President Claudia Sheinbaum reiterated that her government welcomes intelligence sharing but does not permit US agents or forces to participate directly in operations on Mexican territory. Attorney General Ernestina Godoy stated that the investigation determined Jauregui may have engaged in conduct constituting treason by allowing foreign individuals to intervene without authorization on Mexican territory.
