A Satmar leader who raised money for Mayor de Blasio’s 2013 campaign has been busted by the feds for food-stamp fraud, authorities said Thursday.

Yitzchok “Isaac” Sofer, a leader in the Satmar religious group, lied about his income and assets in order to collect more than $30,000 in Supplemental Nutrition Assistance Program funds, according to a complaint unsealed Thursday in Brooklyn federal court.

The activist, who held a fund-raiser for de Blasio in 2013, lied on several SNAP applications between 2012 and 2016, at one point saying he didn’t have a life insurance policy, documents allege.

But Sofer had a $1,000,000 policy and wrote on his Oct. 29, 2012, application for the policy that he had made $100,000 the previous year, according to the complaint.

Sofer was released on $25,000 bail during his Thursday arraignment. He declined to comment.
