Mexico has no proof of links between Mexican drug cartel, Venezuelan President Nicolas Maduro

The allegations linking Maduro to the largest drug cartel in Mexico and the Western Hemisphere came as a surprise to Mexico.

"This is the first time we’ve heard about this issue. There is no investigation from Mexico related to it," said Sheinbaum.

"As we always say, if they have any proof, let them show it. We have no evidence related to that," she said at a news conference.

US President Donald Trump's government accused Maduro of being an international drug kingpin, tying him to transnational criminal organizations such as Venezuela's Tren de Aragua gang and the infamous Sinaloa Cartel in Mexico.

US Attorney General Pam Bondi announced on social media an increase in the reward for information that could lead to Maduro's arrest.

“He is one of the largest narco-traffickers in the world and a threat to our national security. Therefore, we doubled his reward to $50 million,” said Bondi.

The reward was doubled from $25 million offered by the US in January.
