I don't you're aware of what happened at Mara Lago.
Trump took a bunch of government documents, top secret, SCI, and confidential stuff to Mara Lago.
The National Archive noticed. Then they politely asked him several times to return it.
He ignored them.
They came to his place. One of his lawyers said "we searched every room, and we found this one. YOu can have it back." and literally didn't let the government search the hotel.
Because Trump lives in a hotel. Not a secure compound. A hotel.
The National Archive told the DoJ there's a problem. Lots of documents are missing. He gave us access to the CCTV and we can see on the tapes that people are moving boxes in and out of there.
DoJ gets a search warrant. It's approved.
The FBI shows up. Finds 100s of government documents. Some of them top secret, SCI, and stuff so sensitive only a few people in the government are supposed to know about it.
But they were in a carton in Trump's office.
Biden didn't spy on Trump.
The FBI got a warranty because they thought he had stuff he shouldn't have in there.
Turns out, they were right.
