Prosecutors launched the hush-money trial of Donald Trump by revealing new details Monday about how they seek to prove the former president corrupted the 2016 election to bury a sex scandal, while a defence lawyer countered the payment was meant only to protect his reputation.

The trial in lower Manhattan, the first of a former president, involves 34 felony counts alleging Trump falsified business records to cover up a $130,000 payment to porn star Stormy Daniels to stifle her claims of a sexual liaison. Prosecutors say he falsified records by claiming the reimbursements to his former attorney, Michael Cohen, who paid Daniels, were for legal fees.

Prosecutor Matthew Colangelo used his opening statement Monday to sketch out a criminal conspiracy involving Trump, Cohen and David Pecker, who ran the company that owned the National Enquirer and agreed to buy and bury negative news about the former president. The plot, he said, began in a May 2015 meeting in Trump Tower

“The evidence will show this was not spin or strategy but a plan to influence the election to help Donald Trump get elected,” he said. “It was election fraud, pure and simple.”
