Rep. Anthony Brindisi’s office on Friday said an aide arrested on prostitution charges has been fired.

The State Police on Friday afternoon said John A. Stemen, a 57-year-old Utica man, was charged with a third-degree prostitution charge, a misdemeanor.

Stemen admitted to police he had attempted to meet a 17-year-old he contact on the internet and paid $200. He previously worked for the state Assembly, both in Brindisi’s office and for former Assemblywoman RoAnn DeStito, according to his LinkenIn profile.

Stemen served as a case worker in Brindisi’s office.

“As soon as we were made aware of the charges, John Stemen was immediately terminated from his position,” said Brindisi spokeswoman Macey Matthews.

Stemen was issued an appearance ticket and is scheduled to appear in Utica City Court on May 20.

Brindisi, a Democrat, was elected last year, unseating Republican Rep. Claudia Tenney in the district that includes the Utica and Binghamton areas.
