(Bloomberg) — President Barack Obama pledged to veto anylegislation that weakens new curbs on Wall Street as banks and theRepublican-led Congress increasingly seek to roll back theDodd-Frank financial-regulation law.

Obama included the message in his State of the Union speechTuesday after the House approved a measure last week that wouldloosen some restrictions in the 2010 law. His remarks also come asWall Street re-emerges as a force in Washington, havingsuccessfully attached one of its top legislative goals to agovernment spending bill that lawmakers approved at the end of lastyear.

"We can't put the security of families at risk by taking awaytheir health insurance, or unraveling the new rules on Wall Street,or re-fighting past battles on immigration when we've got a systemto fix," Obama said. "If a bill comes to my desk that tries to doany of these things, it will earn my veto."

Congress approved Dodd-Frank in response to the nation's worstfinancial crisis since the Great Depression. Banks and politicianswho opposed it have been counting on Republicans to ease burdens ofthe law that they say are holding back the U.S. economy. On thecampaign trail last year, Senate Majority Leader Mitch McConnell ofKentucky repeatedly referred to Dodd-Frank as "Obamacare forbanks," a play on the president's health- insurance law thatRepublicans have vilified.

Despite Obama's veto threat, he has signed broad bills in recentweeks that included rollbacks of Dodd-Frank. This month, lawmakersin both houses of Congress included a change to the law in a billthat extends a government subsidy for terrorism insurance.

The federal budget bill enacted in December included a provisionthat allows banks to continue trading almost all derivatives indivisions that have government backstops like depositinsurance.
