Eric T. Schneiderman, the top prosecutor in New York, was removed on Tuesday from a committee of state attorneys general investigating mortgage abuses.

In recent months, Mr. Schneiderman has voiced concerns over a proposed settlement between major banks and a coalition of federal and state officials over claims of foreclosure abuses. He has come under increasing pressure to approve the deal.

The Iowa attorney general’s office is leading the investigation and on Tuesday sent an e-mail to other lawyers involved in the investigation to announce the decision. “Effective immediately, the New York attorney general’s office has been removed from the executive committee of the robosigning multistate,” a lawyer from the Iowa office wrote, using the shorthand for the investigation, which is looking into so-called robo-signing of mortgage documents and other abuses.

Mr. Schneiderman has said that he opposes any deal that gives participating banks a release from other litigation surrounding their mortgage activities. Attorneys general from other states have also questioned aspects of the deal, including Beau Biden of Delaware.
