Secret Service officials are angered that FBI Director Kash Patel prematurely announced on Tuesday the details of a largely sealed and ongoing criminal investigation into an alleged plot to attack Sunday’s White House UFC event with drones, according to three people familiar with the incident.

Secret Service and FBI agents had been partnered on the investigation into a group of individuals discussing plans for a drone attack at the White House in the last week, and had discussed unsealing the case and making a joint announcement Tuesday afternoon, according to sources.

The problem with Patel’s social media announcement, the sources say, was that the case had been sealed in court and roughly 10 suspects had not yet been arrested and placed in custody at the time Patel shared his post. The people said Secret Service and FBI officials were surprised by Patel “jumping the gun.”
