A pro-Bernie Sanders group on Monday announced its backing of Democratic state Senate candidate Alessandra Biaggi, who is running a primary campaign against Sen. Jeff Klein.

Biaggi is being endorsed by People for Bernie in her bid to defeat Klein, the former leader of the now-defunct Independent Democratic Conference.

“I’m thrilled to be supported by The People for Bernie,” Biaggi said. “Not only do we have a shared vision for the future – the organization and our campaign are both built on grassroots ‘people power.’”

The IDC folded in April and its members joined the mainline conference fold. But that has not deterred the previously announced primary challengers to several IDC lawmakers.

The agreement for the IDC to dissolve left Klein as the deputy minority leader in the state Senate. Klein earlier this year was accused of sexual harassment by a former staffer. Klein has denied the allegation and the Joint Commission on Public Ethics is investigating.

“We are enthusiastically endorsing Alessandra,” said Kat Brezler, co-founder of The People for Bernie. “Biaggi has been knocking all the doors in the District where grew up. This is the work it takes to win election – not backroom deals that have been the cornerstone of her opponent’s process.

Klein, meanwhile, over the weekend was endorsed by the Hotel Trades Council, a union endorsement the came after he was backed by RWDSU.

“The Hotel Trades Council proudly stands with Jeff Klein and strongly endorses his reelection to the New York State Senate,” said New York Hotel and Motel Trades Council President Peter Ward. Jeff Klein is a proven leader, who fights tirelessly—and delivers—for labor and all of New York’s working families. We need his continued leadership in Albany.”
