We know that the New York investigation into Donald Trump’s business and some of his associates has been ramping up in recent months. Now the Wall Street Journal reports that Trump’s former bodyguard Matthew Calamari is under the microscope.

According to the WSJ:

Prosecutors’ interest in Mr. Calamari, once Mr. Trump’s bodyguard, indicates that their probe into the Trump Organization’s alleged practice of providing some employees with cars and apartments extends beyond Allen Weisselberg, the company’s chief financial officer, and his family. Neither Messrs. Calamari and Weisselberg nor anyone else connected to the company has been accused of wrongdoing.

Receiving benefits—such as free apartments, subsidized rent or car leases—from an employer, and not paying taxes on such benefits, can be a crime, although experts said prosecutors rarely bring cases on such perks alone.
