The Latest on the U.S. trial of Mexican drug lord Joaquin "El Chapo" Guzman (all times local):

1 p.m.

A government witness has been testifying about the lavish spending habits of the Mexican drug lord known as "El Chapo."

Former cartel member Miguel Angel Martinez told a jury Tuesday at the New York trial of Joaquin Guzman (wah-KEEN' el CHAH'-poh gooz-MAHN') that the "cocaine boom" of the early 1990s made Guzman so wealthy that he had a private zoo at his ranch in Guadalajara.

The witness says Guzman bought a $10 million beach house in Acapulco. He also said the defendant once traveled to Switzerland for an anti-aging treatment.

Guzman has pleaded not guilty to drug-trafficking charges. He says he's being framed.
