Manhattan’s district attorney has hired a top prosecutor who specialises in white-collar and organised crime to join its investigation into Donald Trump and his businesses.

Mark Pomerantz, who has a long career as a federal prosecutor and trial attorney, was sworn in on February 3 as an assistant district attorney, Danny Frost, a spokesman for the Manhattan district attorney’s office, told Insider.

The New York Times first reported the hire.

Pomerantz has joined the team assembled by District Attorney Cyrus Vance to investigate whether the Trump Organisation committed insurance and tax fraud, and falsified records.

Reuters reported that in his new role, Pomerantz interviewed Michael Cohen, Trump’s former personal attorney and fixer, on Thursday.

Insider has contacted the Manhattan District Attorney’s Office for confirmation of the hire.

In court documents, the office has said that its investigation is focused on “possibly extensive and protracted criminal conduct” at the Trump Organisation, the umbrella company for Trump’s various business interests.

Trump has long denied any wrongdoing, claiming that the investigations are politically motivated.

Vance’s investigation is the only known criminal probe being conducted into Trump’s business dealings, with a civil probe by New York Attorney General Letitia James investigating whether Trump falsely reported property values to secure loans and tax benefits.

Pomerantz has several decades of experience as a trial lawyer and litigator, having led the criminal division of the US Attorney’s Office for the Southern District of New York between 1997 and 1999.

During his time in the job he oversaw the prosecution of several organised-crime cases, including that of John A. Gotti, the son of the Gambino crime family boss John J. Gotti, on racketeering charges. According to The Times, Pomerantz was involved in the 1988 case which established the legal definition of racketeering, which has been used to prosecute organised-crime figures.

After his stint at the US attorney’s office, Pomerantz then moved into private practice.

According to his profile on the University of Pennsylvania’s website, where he serves on the advisory board for the Quattrone Centre for the Fair Administration of Justice, Pomerantz has “has handled major matters and internal investigations involving all aspects of alleged corporate misconduct, including securities and bank fraud, mail and wire fraud,” as well as organised-crime offences, tax crimes and bribery.
