At the request of the FBI, County Executive Mike Callagy in September sent a federal agent a copy of a lease for a Redwood City property rented by the Sheriff’s Office. The lease was attached to an email obtained by the Bay Area News Group through a public records request.

The existence of the email confirms, for the first time, rumors swirling for months that the FBI had been in touch with county officials about the Sheriff’s Office.

In an interview Tuesday, Callagy declined to discuss in detail the brief email or any other communication with the FBI. He said he did not believe he had been contacted again by a federal agent since.

“I was asked for the documents, and I sent the documents,” he said.

The report, conducted by an independent auditor at the request of county officials, claimed that Corpus’ former chief of staff and alleged romantic partner, Victor Aenlle, had a conflict of interest in negotiating the lease because he was both a county employee and a licensed real estate agent with the company that brokered the deal. The report suggested he could have profited from the agreement.
