"walk off with them" - President Trump kept the classified documents in the same place where they were authorized to be during his Presidency. He did not take them anywhere. You seem to be aware that there is a very involved process for Presidents to get documents in coordination with the National Archives for their Presidential Libraries, and how difficult it can be. Trump kept the documents in the same place they had been authorized to be while he was going through this same process. And you seem to be entirely ignoring the fact that Trump had had unilateral authority to declassify them while he was President. This is a complex issue that has been weaponized by the same Democrats in charge of the FBI who worked with Hillary Clinton's paid misinformant to fabricate Russian lies about Trump to have the FBI spy on Trump going into his Presidency. The Democrats have been abusing our system of law for a while now to destroy political enemies.
