Trump's attorney challenged Stormy Daniels' narrative of a 2006 sexual encounter with Trump, aiming to highlight inconsistencies in her various accounts. The effort was to discredit her as a witness in the first-ever criminal trial involving a sitting or former U.S. president.Daniels' detailed description of the encounter, which occurred in a Lake Tahoe hotel suite while Trump was married to Melania, captivated jurors and stirred memories of the more sensational aspects of his presidency from 20
None of it matters (what happened, or even if it happened) in a legal sense except that Trump committed election fraud (a felony in NY) due to the manner and timing of the payoff to Daniels.
The purpose of Daniels testifying is to establish that there was good reason to pay her off, that indeed, the nature of the allegations - whether true of not - would have influenced the 2016 elections, as did silencing Daniels with the payoff under question. This establishes the motive for the alleged crime, which elevates a misdemeanor business fraud charge to a felony election fraud charge.
