I'll try one more time since you're obviously very slow on the uptake.
The payoff happened in 2016.
None of this was even discussed until just a couple months ago.
Trump has said all along he had no idea what Cohen had done or why.
Everything Giuliani is saying now fits that narrative exactly.
So as things stand, Trump is free and clear and has no issues.
The only thing that will change that is if somewhere in all of Cohen's shit they took they find some correspondence between the two of them discussing paying her off or it could screw the campaign over. Short of that, the only other thing that would even have a chance of getting Trump in trouble would be if Cohen himself testified that Trump told him to pay her off for that reason.
Other than that, it's all worthless news shit to get people like you in an uproar...and it works well, obviously.
