The United States has sanctioned a son of Mexican drug lord Joaquin “El Chapo” Guzman, three members of the Sinaloa cartel and two Mexican-based firms, alleging they trafficked fentanyl and other drugs into the U.S. Tuesday's sanctions came the day Mexican President Andrés Manuel López Obrador talked with President Joe Biden about immigration and the fentanyl crisis.

Mexico’s president said Wednesday his government will consider a plea by imprisoned drug lord Joaquin “El Chapo” Guzman to be returned to Mexico, presumably to serve out his sentence.

NEW YORK - The notorious Mexican drug kingpin Joaquin "El Chapo" Guzman has been sentenced to life behind bars in a U.S. prison. A federal judge in Brooklyn handed down the sentence Wednesday. The 62-year-old drug lord was brought to the U.S. to stand trial after he twice broke out of Mexican prisons. The guilty verdict triggered a mandatory sentence of life without parole. Guzman told U.S. District Judge Brian Cogan before he was sentenced Wednesday that he was denied a fair trial.

But if the appeal is not successful, "then this will be the last time the public will see El Chapo," Colon told CNN. "It could be potentially also the last time El Chapo could see his wife." He is limited to phone calls and visits from certain family members, including his twin 8-year-old daughters. In 2001 Guzman escaped by hiding in a laundry cart. Guzman escaped from the Mexican prison a second time, on July 11, 2015.

(CNN) - A federal judge in New York Wednesday denied drug kingpin Joaquin "El Chapo" Guzman's bid for a new trial. The count of engaging in a continuing criminal enterprise carries a mandatory term of life in prison. Defense attorney Jeff Lichtman, in a statement, said Wednesday that the ruling further demonstrated the trial "was more of an inquisition, a show trial, than an exercise in true American justice." In March, Guzman's attorneys asked Cogan for a new trial and to recall the jurors back for an evidentiary hearing to find out if there had been misconduct. Prosecutors responded that the court's repeated instruction to jurors, their diligence during the trial, and overwhelming evidence against Guzman show that "the alleged media exposure did not prejudice the defendant."
