After years as one of U.S. authorities' most wanted men, Mexican drug cartel boss Rafael Caro Quintero was brought into a New York courtroom Friday to answer charges that include orchestrating the 1985 killing of a U.

Mexican drug lord Rafael Caro Quintero appeared before a judge in Brooklyn on Friday afternoon, pleading not guilty to charges related to his involvement in the decades-old killing of a Drug Enforcement Administration agent.

Canada and Mexico are trying to get the United States not to follow through on a promise by President Trump to impose tariffs of 25% on imported goods.

Mexico has sent Quintero and 28 other cartel figures to the U.S. as the Trump Administration turns up the pressure on drug trafficking organizations.

Rafael Caro Quintero was arraigned on multiple drug and weapons offenses in Brooklyn federal court following his extradition Thursday to the U.S. from Mexico.
