Republican attorney general candidate John Cahill’s campaign finance filing this week shows Home Depot founder and prolific GOP donor Ken Langone and wife Elaine Langone contributed a combined $82,000 his effort to unseat Democratic incumbent Eric Schneiderman.

Ken Langone, no stranger to making blunt statements that occasionally garner some controversy, contributed $41,000, while Elaine Langone also cut a $41,000 check, records show.

He is also part of a Republicans For Cuomo organization and has spoken favorably of Democratic incumbent Gov. Andrew Cuomo

Ken Langone has pointed to education — especially his support for charter schools — as a top policy issue. Cahill, a former top aide to ex-Gov. George Pataki who is now his law partner, has made education issues a key plank in his campaign.

Joan Cooney, one of the co-creators of “Sesame Street” contributed $41,100.

Records show the former governor contributed $5,000 to Cahill’s effort, while their law practice Pataki-Cahill Group also donated $5,000.

Republican gubernatorial candidate Rob Astorino’s campaign contributed $1,000.

Overall, Cahill raised more than $1 million for his campaign that started in May.
