The judge summarized the case for the jury as follows:
> The allegations reflect in substance, that Donald Trump falsified business records to conceal an agreement with others to unlawfully influence the 2016 presidential election. Specifically, it is alleged that Donald Trump made or caused false business records to hide the true nature of payments made to Michael Cohen, by characterizing them as payment for legal services rendered pursuant to a retainer agreement. The People allege that in fact, the payments were intended to reimburse Michael Cohen for money he paid to Stephanie Clifford, also known as Stormy Daniels, in the weeks before the presidential election to prevent her from publicly revealing details about a past sexual encounter with Donald Trump.
That summary implies that paying off Stormy Daniels "to prevent her from publicly revealing details" about the affair was the unlawful act. But under what law? And why wasn't he just charged with that law directly?
