Senator Charles E. Schumer, Democrat of New York, who helped lead the opposition to Dubai’s investment in the American ports, said last night that the deal, which would make Dubai a major player in New York finance, would “raise serious questions that have to be answered.”

“Should any government own any part of a major U.S. stock exchange?” asked Mr. Schumer, who is on the banking and finance committees in the Senate and is the chairman of the joint House and Senate economic committee.
