Kate del Castillo: Mexican Government Wants Her for Questioning in El Chapo Case

Kate del Castillo is now wanted for questioning by the Mexican government, and TMZ has learned the case involves tequila and alleged money laundering.

Kate -- who interviewed El Chapo while he was on the run -- is an investor in Tequila Honor, and our sources say the government wants to know if El Chapo secretly invested in the company and the money he put in was laundered.

The government wants to question Kate and if she returns to Mexico they could detain her for that purpose. Sources connected with Kate tell us, although she'd like to go back to Mexico to visit family, she will not return until the investigation is closed. She lives in L.A.
