The Working Families Party on Thursday endorsed a trio of women running challenges to members of the Independent Democratic Conference.

The labor-aligned party endorsed Democrats Rachel May against Sen. David Valesky of the Syracuse area, Alessandra Biaggi against Sen. Jeff Klein, the conference leader, and Jessica Ramos against Sen. Jose Peralta of Queens.

The endorsements were linked to the ongoing #MeToo reckoning surrounding sexual harassment and misconduct. Klein, a Bronx lawmaker, has been accused of forcibly kissing a former aide; a charge he denies and has pushed for an investigation into the claim.

Klein has also backed Gov. Andrew Cuomo’s proposed changes to the state’s sexual harassment laws, which include more money for investigations and a ban on secret, taxpayer-funded settlements.

“The WFP is putting its organizing muscle behind these three progressive women reformers — Alessandra, Rachel, and Jessica — who are ready to support Democratic Leader Andrea Stewart-Cousins on Day 1,” said WFP Director Bill Lipton. “We will raise thousands of grassroots donations and work with activist groups across New York to make sure our message reaches every voter in these districts.”

The endorsements also come as mainline Democrats in the state Senate are avoiding support for IDC challengers as an uneasy truce remains in effect stemming for a unity deal agreed to last year that would be triggered if Democrats win a pair of special elections scheduled for April 24.

In a statement, IDC spokeswoman Candice Giove blasted the WFP.

“Since its creation in 1998 the Working Families Party has become a travesty whose objective is to destroy the Democratic Party for its sole political interests. What used to be a champion of Working Families has become a corrupt political enterprise,” she said. “The Independent Democratic Conference is happy to put its record of accomplishments — a $15 minimum wage, a $10 million dollar immigrant legal defense fund and the strongest paid family leave program in the nation — against the do nothing Working Families Party.”
