Did they go after 0bama for the documents he took? They are going after internal FBI memos showing that they helped orchestrate the Russia Collusion hoax (that Trump declassified, but the FBI refused to make public). All because Trump is suing some of the individuals involved.
That's exactly what they were after. Sadly, they may have found them and destroyed them by now. I wonder if Trump had a list?
Also note, whether still classified or not, Trump kept the files in a safe! Mrs. Bill Clinton kept Secret and Top-Secret files on her unsecure private server, when legally she was supposed to use a secure government server. Anyone who thinks the Russians and others didn't copy those free-for-the-taking files in a naive fool.
