What are the US secret drone operations over Mexico targeting?

According to US officials, the United States has intensified secret drone flights over Mexico specifically to locate and monitor fentanyl labs. This initiative is part of a broader aggressive campaign against drug cartels that began during the Trump administration but reportedly became operational under the Biden administration. The previously undisclosed drone program represents an escalation in US intelligence operations aimed at combating the fentanyl crisis. While initiated under Biden, Trump and his CIA director John Radcliffe have promised even more intense action against Mexican drug cartels, indicating the bipartisan nature of this approach to addressing drug trafficking from Mexico.
