Senate Republican leaders said Democrats are pushing a financial-regulation bill that provides a permanent taxpayer bailout for Wall Street banks, setting the stage for a partisan fight on the White House plan.

The bill advanced by the Senate Banking Committee on a party-line vote last month would “enshrine” the idea that some financial companies are too big to fail, Senator Richard Shelby (R-Ala.) said at a news conference in Washington.

“It institutionalizes and sets up in perpetuity taxpayer funding of bailouts,” Senate Minority Leader Mitch McConnell, (R-Ky.) said in Washington. “That’s not something Republicans are likely to agree to.”

Senate Banking Committee Chairman Christopher Dodd, (D-Conn.) who wrote the bill, is seeking a compromise with Shelby that would attract Republican votes when it is debated on the Senate floor in the coming weeks.

At issue is a provision in Dodd’s bill that would enable the government to unwind systemically important financial firms whose collapse could threaten the economy.
