Months after the collision between a U.S. Army helicopter and a passenger jet that killed 67 people in Washington, D.C., Congress and federal aviation safety regulators are still investigating what happened.

In the immediate aftermath, as the Trump administration scrambled to blame the tragedy on diversity, equity, and inclusion policies, authorities took swift action against two men they accused of leaking dramatic footage of the crash to CNN, which aired videos that appeared to come from Ronald Reagan Washington National Airport’s security cameras.

The charges, filed by local authorities in Virginia, came as President Donald Trump and his allies vowed to crack down on journalists and their sources.

But on Wednesday, local prosecutors in Virginia dropped charges entirely against one of the men, Jonathan Savoy, who worked at the Metropolitan Washington Airports Authority. The second MWAA employee, Mohamed Mbengue, indicated he would not contest the charges, according to court records, reportedly as part of a pretrial diversion agreement with prosecutors.
