U.S. lawmakers and lobbyists who once backed repeal of the 2010Dodd-Frank Act are now pushing for technical fixes to the law, andthey're getting a skeptical reception from the measure'sadvocates.

While some alterations to the act have bipartisan support inCongress, many Democrats say they remain wary of measures thatmight undermine the law that created the Consumer FinancialProtection Bureau and mandated regulations to curb risky behaviorby financial institutions deemed too big to fail.

“There is general agreement that technical corrections on an800-page bill would be appropriate,” said Lauren Kulik, aspokeswoman for Senator Sherrod Brown, a Democrat from Ohio and amember of the Senate Banking Committee. At the same time, she said,Dodd-Frank supporters worry that a technical change could “morphinto a substantive change.”
