CBS, or really any news organization or reporter, can't BREAK a story without knowing about the story. So at some point, somebody leaked it to the press. Probably that damn official White House statement.
But who violated what laws when? Did Biden take classified docs to the VP residence? That wasn't reported at the time, that I remember.
Did the VP have classified docs in his office at the White House? This is more likely. And seems necessary. So, probably no laws broken at this stage.
Then, the VP office at the White House was packed up, and the boxes taken away. Everything in the office was boxed up. Whoever boxed up the office probably didn't rummage through papers, to see if any classified docs were among the other stuff.
As soon as the docs were discovered, they should have been reported to the proper authorities. By all indications, this was done. Proper procedures were followed.
Yes, there should still be a Congressional Committee to look into those docs. They can compare them with the Trump docs, as far as the hows and whys.
But I still think anything this does to Biden, it does to Trump even more.
