A Treasury Department spokesman also rejected the rumors on Friday.

“There are a lot of rumors in the market, as always, but you should not regard these as any indication of the policy of this administration,” said the spokesman.

As Treasury Secretary Timothy Geithner has said, “we will preserve a financial system that is owned and managed by the private sector,” he said.

The U.S. government has already provided significant aid to Citigroup and Bank of America in its efforts to save the nation’s financial sector, which has been choked by bad assets.
