Embattled city Comptroller John Liu’s campaign treasurer is trying to cut a deal with the feds over charges she steered illegal contributions into his campaign war chest, according to court papers filed yesterday.

Prosecutors “have had discussions regarding a possible disposition of this case” with lawyers for Jia “Jenny” Hou, but “the negotiations have not been completed,” the papers say.

“We plan to continue our discussions but do not anticipate a resolution before [yesterday’s] deadline under the Speedy Trial Act,” Manhattan federal prosecutor Brian Jacobs wrote.

Magistrate Judge Henry Pitman extended the deadline for Hou’s indictment until April 30.

Neither side would discuss the details of the negotiations or say if Hou planned to turn on Liu.

Earlier this month, the Democratic comptroller acknowledged that the feds were likely aiming at a bigger target than Hou, but insisted, “I’ve done nothing wrong and I’ve got a clear conscience.”
