Two more staffers in the office of former Brooklyn District Attorney Charles Hynes were slapped with fines on Wednesday for working on his failed 2013 re-election campaign on city time or using city resources — bringing the total number of former staffers fined for campaign work to 10.

The city Conflicts of Interest Board fined former deputy DA Dino Amoroso $4,500 for using his work email and computer to prepare Hynes for TV appearances, discuss debate performances and analyze campaign canvass reports between April and September 2013.

The week after Hynes lost his primary to Democratic rival Kenneth Thompson, Amoroso also brainstormed with Hynes about how much money he’d have to raise to compete against Thompson on the Republican line — a bid Hynes ultimately undertook.

He then lost for a second time.

Thompson became the district attorney but died in office in October 2016.

Hynes’ liaison to the LGBTQ community, Marc Fliedner, was fined $800 on Wednesday for campaign work related to securing endorsements for Hynes from the gay community in 2013.

Hynes himself was hit with the highest campaign-related fine ever levied by the COIB in March, a $40,000 penalty for turning his prosecutorial office into his re-election team.

Four of his top staffers were collectively fined $14,500 at that time, while an additional three were fined $5,600 collectively in June.

Fliedner and Amoroso couldn’t immediately be reached for comment.
