Correct they can't do that and most certainly should not do that, including Trump!
But to charge any of them under the U.S. Code in the Espionage Act, they had to KNOWINGLY take them, and Knowingly retain them and not return them to the government when found or asked. Neither Joe or Pence, knowingly took them and then knowing kept them once they were found... there was no intent.
Former president Trump DID BOTH, knowingly....with intent....he took the marked classified government documents and retained them, illegally and when asked by our govt to return them, he didnt.
Trump made his own problem..... He made the bed he chose to sleep in.
