In the official record, the case is known as the People of the State of New York v. Donald J. Trump, and, for now, the people have the stronger hand: They have insider witnesses, a favorable jury pool and a lurid set of facts about a presidential candidate, a payoff and a porn star.
On Monday, the prosecutors will formally introduce the case to 12 all-important jurors, embarking on the first prosecution of an American president. The trial, which could brand Mr. Trump a felon as he mounts another White House run, will reverberate throughout the nation and test the durability of the justice system that Mr. Trump attacks as no other defendant could.
Though the district attorney, Alvin L. Bragg, has assembled a mountain of evidence, a conviction is hardly assured. Over the next six weeks, Mr. Trump’s lawyers will seize on three apparent weak points: a key witness’s credibility, a president’s culpability and the case’s legal complexity.
Prosecutors will seek to maneuver around those vulnerabilities, dazzling the jury with a tale that mixes politics and sex, as they confront a shrewd defendant with a decades-long track record of skirting legal consequences. They will also seek to bolster the credibility of that key witness, Michael D. Cohen, a former fixer to Mr. Trump who previously pleaded guilty to federal crimes for paying the porn star, Stormy Daniels.
Daniel J. Horwitz, a veteran defense lawyer who previously worked in the Manhattan district attorney’s office prosecuting white-collar cases, said prosecutors can be expected to corroborate Mr. Cohen’s story wherever possible.
