I've been thinking about this, what if when he said Jan 6 was a terrorist attack, he did it intentionally to have it on public record.
If he legally proves the feds were involved in the Jan 6 as they like to call it "insurrection," they can be classed as terrorists as well as whoever gave the command to breach the capitol barricade (Ray Epps).
That would be a brilliant move, but I don't think it was that thought out. He wanted to avoid all of this. "Look at the wives." He is doing better now
