(CNN) Michael Cohen and his attorney met Wednesday with a group of state and federal law enforcement officials investigating various aspects of President Donald Trump's family business and charitable organization, according to people familiar with the meeting.

The group, which included the federal prosecutors from the US Attorney's Office for the Southern District of New York who charged Cohen in August and officials from the New York Attorney General's office, met at the Midtown New York City office of Cohen's attorney, Guy Petrillo, these people said.

CNN observed Cohen leaving Petrillo's office building Wednesday afternoon. Assistant US Attorney Tom McKay, the lead prosecutor on the Cohen case, had entered the building earlier in the day.

The purpose of the meeting wasn't immediately clear, but both offices are continuing to investigate cases that relate to Trump entities and with which Cohen had professional involvement.

Representatives for both the attorney general's office and the US attorney's office declined to comment. Petrillo didn't immediately respond to a request for comment.
