The top state prosecutor in Jacksonville, Fla., is trying to derail her former boss’s bid to become Middle District of Florida U.S. Attorney, The Times-Union newspaper reported Sunday.

The nasty feud between current State Attorney Angela Corey and former former State Attorney Harry Shorstein in Jacksonville is personal. Two years ago, Shorstein fired Corey and later publicly opposed her bid for election to the state prosecuting job, the newspaper said. But last year, Corey trounced Shorstein’s former chief of staff in the bitterly contested election.

Now Shorstein, who is name partner at the Jacksonville law firm Shorstein & Lasnetski, is one of three finalists for the Middle District job. And Corey has written to Florida’s U.S. senators to ask them not to recommend her former boss to President Obama, the newspaper said. A recommendation is expected to be sent this month.

“I told them he should not hold a position of authority in his community again because of his penchant for using the grand jury for personal vendettas,” Corey told The Times-Union.

And earlier this year, Corey’s deputy, Chief Assistant State Attorney Dan McCarthy, circulated an email to staff recounting negative remarks that Times-Union readers had posted about Shorstein on the Web version of the newspaper’s story about his U.S. Attorney bid, the newspaper said.

Corey also told the newspaper last month that she wouldn’t speak with Shorstein if he’s appointed the top federal prosecutor. But Shorstein told The Times-Union he doubted Corey would fail to cooperate on joint investigations or other law enforcement matters if it became “detrimental to the people.”
