Senior Mexican government officials are attending a flurry of meetings with U.S. counterparts in Washington this week as bilateral tensions simmer over tariffs, drug gangs and migration. Mexican Economy Minister Marcelo Ebrard will meet on Thursday with U.

MEXICO CITY (AP) — Mexico has sent drug lord Rafael Caro Quintero, who was behind the killing of a U.S. DEA agent in 1985, to the United States with 28 other prisoners requested by the U.S. government, the Mexican government said in a statement Thursday.

President Claudia Sheinbaum also said Mexico will expand its legal action against U.S. gun manufacturers following the decision to designate drug cartels as terrorist organizations.

Among those flown to the U.S. today was Rafael Caro Quintero, a founding member of the Sinaloa drug cartel who was convicted in Mexico of having masterminded the 1985 murder of the D.E.A. agent Enrique Camarena. For decades, American officials have obsessed over getting hold of him.

Senior Mexican security and diplomatic officials will meet with U.S. Secretary of State Marco Rubio in Washington on Thursday, President Claudia Sheinbaum told reporters on Wednesday, as bilateral tensions over drug gangs and migration simmer.
