If Trump wants to show how out of control FBI is, he just needs to release the search warrant. He has a copy and it names the specific crime and the basis for probable cause.
Just remember, the only reason we're in this mess is that Trump has always been shameless about (seemingly) catering to the rabid mob's legitimate concerns that have gone ignored for generations by other politicians. They are desperate and he appeared to be throwing them a bone no one else would.
So the "big bad" FBI raided the Flori-DUH home of the widdle ol' Orange doG because he has in his possession classified documents that did not belong to him and now he's complaining that they, the FBI, are out of control?
Brianna Taylor and her family wish they had that problem when the cops came raiding and shooting up her apartment......
PS - Yes, I know that the FBI and Louisville cops are separate entities.
Besides the Presidential Records Act, which Charles mentioned, Trump may have also violated the Espionage Act of 1917. If anyone thinks that's long outdated, its how they nailed Edward Snowden.
JMS has an interesting theory/speculation without anything to back it up.
The surprise nature of this being due to something found on Alex Jones phone indicating that something might be @ the complex that might be destroyed such as documents or a burner phone.
Trump may have broken some laws taking the top secret documents out of the WH, some people involved in national security, don't think he will get prosecuted especially if all the files are recovered. There wouldn't be much of a point.
it's highly unlikely any single "smoking gun" will turn up in criminal investigations of Trump's activities. But as with most criminal probes, it is an accumulation of evidence that makes the case.
