We see in politics that whenever someone doesn’t want to get into details they frequently use “I can’t comment further because there is an ongoing investigation”. Whether Sarah was being truthful regarding the FBI or not, it’s clear they didn’t want to get into specifics regarding the leaked photos/videos. Other than to say there was no consent and she trusted someone she shouldn’t have.

Then she says this about the FBI and basically gives the spiel about an “ongoing investigation” so she can’t comment further. Like there was some kind of gag order imposed on her lol. They may be using a gag in the future but in a very different way.
