New York prosecutors have continued to pressure top Trump Organization executive Matthew Calamari to cooperate since charging the company and its chief financial officer earlier this month, according to a person familiar with the matter – the latest sign that the inquiry is continuing.

Calamari, the chief operating officer of the Trump Organization, is among a small group of top company executives with a close relationship to Trump who could possibly help prosecutors in their ongoing investigation.

Two years into the criminal investigation, prosecutors do not appear to have convinced anyone who works at the Trump Organization to cooperate against former President Donald Trump, according to a person familiar with the matter.

Prosecutors started talking to Calamari’s legal team before the indictment and have continued those discussions in the two weeks since it was unsealed by a Manhattan judge.
