How bad does the Mar-a-Lago document situation have to get before it becomes a problem for President Trump?

The answer is very bad and probably much worse than what we know of today. In the three weeks since the raid at Mar-a-Lago, we've learned very little about the contents of the documents that former President Trump is alleged to have improperly been storing in his Florida compound.

But we have learned, at a minimum, he kept classified documents outside of a secure facility. And the government is now alleging that Trump's legal team lied about the number and nature of the documents being stored there, which made it much more difficult for them to get the documents back and set up the premises for this sensational raid at Mar-a-Lago.
