New York’s attorney general is investigating a charity tied to Queens Assemblywoman Vivian Cook, The Post has learned.

The AG’s Office dispatched a team of investigators last week to a parking lot owned by the Rockaway Boulevard Local Development Corp., a source familiar with the investigation told The Post.

“I don’t know nothing about the attorney general,” Cook told The Post last week.

The probe comes a week after The Post revealed that the defunct charity, founded by Cook in 1979, is collecting thousands from the rental of the once-empty and derelict lot — purchased with millions in public funds — to construction companies for vehicle storage. Who is pocketing the rental money remains a mystery.

Cook’s charity shut down in 2010 after The Post exposed its wasteful spending.
