Aren’t these the guys she’s supposed to be putting away?

Queens Borough President Melinda Katz boosted her campaign for district attorney by holding a fund-raiser at a mobbed-up eatery in Rego Park, The Post has learned.

Sources said Katz partied with supporters Tuesday night at the Barosa Italian restaurant, which is co-owned by reputed Genovese associate Frank Barbone.

Barbone, 47, has twice been convicted in illegal-gambling cases, including one in Queens for which he served a 1 ¹/₂ to 4 ¹/₂- year prison term.

He’s currently on supervised release in the other — in which he admitted to a Manhattan federal judge that gangsters might drop by his place from time to time.

Barone was present at the restaurant during Katz’s fund-raiser, for which tickets cost $150 each, sources said.

“Shouldn’t she know where the owner is a mobster?” a source wondered.

In 2016, Barbone was among 46 reputed gangsters busted in what the feds called a “sprawling and long-running racketeering conspiracy” that involved four of New York’s “Five Families,” as well as the Philly mob run by Joseph “Skinny Joey” Merlino.

Prosecutors said Barbone ran an illegal sports-gambling operation with reputed Genovese member Alex Conigliaro, with whom he was also convicted in 2000 on state gambling charges.

In 2017, Barbone struck a plea bargain that got him a one-day, time-served jail sentence, and three years supervised release.

As part of that deal, he was also ordered by the judge “not to associate with anybody who is affiliated with a gambling enterprise, a crime syndicate, an organized crime family.

“You know who I am talking about,” Manhattan federal Judge Richard Sullivan told Barbone during his sentencing.

To that, Barbone asked what to do “if somebody comes to eat in the restaurant,” and suggested, “don’t sit with them, walk by?”

“I think that’s fair,” said Sullivan. “I mean, you can’t be hanging and playing wiseguy with people — you just can’t.”

Katz campaign spokesman Grant Fox said: “It’s surprising that Melinda’s opponents, who are tripping over themselves claiming to be reformers, are floating this kind of half-baked opposition research to hurt someone who paid his debt to society and now runs a popular restaurant that has hosted events for candidates on both sides of the aisle.”
