Project Cassandra is an effort led by the United States Drug Enforcement Administration (DEA) to undercut Hezbollah funding from illicit drug sources. Launched in 2008, the project was said to be investigating the terrorist organization's funding. According to the DEA, Hezbollah has become increasingly involved with drug trafficking and organized crime as a method of funding its activities. The investigation was tracking how large sums of money were being laundered from the Americas, through Africa, and to Lebanon into Hezbollah's coffers. 
An investigative report published by Politico in December 2017, described how, during the Obama administration, national security concerns regarding the Iran nuclear deal took precedence over the DEA project.
In January 2018, Fox News confirmed that Bruce Ohr has been fired as the head of the Organized Crime Drug Enforcement Task Force (OCDETF). As the head of OCDETF, Ohr was directly involved with Project Cassandra.
