Stormy Daniels was paid before the election then repaid after it, otherwise, how could Trump be accused of hiding the payments to influence the election, fool
Cohen's payment to Stormy right before the election to hide Trump's tryst with Stormy, so not to interfere and hurt his presidential candidacy was illegal. The maximum Cohen could donate to personally help the Trump campaign was limited under campaign finance law to +/- $3000 or in kind donations an election cycle, $130,000 exceeded his limit ...and Cohen was convicted for this crime in 2019.
The election was over as you say, but Trump's falsified business records were to cover up Cohen's crime.... of an over limit, campaign finance donation. This is what he was convicted for and found guilty for....
So in other words, these records never could have "influenced" the election without New York State climbing down Trump's shorts on a witchhunt LOOKING for a crime to prosecute him on, THEN releasing it to the public themselves hoping to damage HIS election, the very thing they accused HIM of trying to do.

nope! Cohen's indictment included individual#1, Trump. They didn't have to make up a crime or scour his books to find one. They had to wait until Trump was no longer President to pursue the investigation in to Trump, Individual#1
You cannot prove what is in a man's mind, just as you cannot prove he had no other motivation, like protecting his wife.
They proved it ....beyond a reasonable doubt in the trial, through more than a handful of witness testimony.... Pecker, Cohen, Hope Hicks, Secretaries, Accountants, etc.
Sure they did. Merchan made the rules so broad in that case to include subjecting Trump to cross on EVERY OTHER CASE AGAINST HIM CURRENTLY PENDING that the risks and complications were so high in testifying in his behalf that it inhibited his defense, just as they disallowed many other aspects of his defense such as not allowing an expert from the Federal Elections Committee to testify that in their opinion, what Trump did was no crime to the elections board. Swing and a miss
Merchan listened to the prosecutors reasons for needing and using these other things and the defense team arguments against them, and based on those arguments by both sides, made the judgement that those things could be related and questioned by prosecutors when Trump was on the stand.
Trump was well aware of this when he was making the claim that he would testify....only to back down, as we all knew he would, using this as an excuse, as if he didn't know all along those other issues could be brought up while he was under oath.
Why did that scare him so much?
