One of the co-founders of the infamous Sinaloa Cartel, El Mayo, has pleaded guilty to drug trafficking charges and will serve time in a US federal prison, in a major victory for President Trump's cartel crackdown.

El Mayo, whose real name is Ismael Zambada Garcia, entered his guilty plea in a US courtroom on Tuesday, admitting to his role in smuggling massive quantities of drugs across the US-Mexico border. The US Attorney General, Pam Bondi, hailed the guilty plea as a significant step towards justice.

"El Mayo will die in the US federal prison where he belongs," said AG Bondi. "This sends a clear message to other members of the Sinaloa Cartel and other drug trafficking organizations that their crimes will not go unpunished."

President Trump's administration has been cracking down on cartels, and El Mayo's guilty plea is seen as a powerful political leverage. It serves as a warning to those who continue to engage in illegal drug trafficking activities.

El Mayo's guilty plea and upcoming imprisonment mark a turning point in the fight against cartels, as US authorities continue to work towards dismantling these criminal organizations.
