President Barack Obama pledged to veto any legislation that weakens new curbs on Wall Street as banks and the Republican-led Congress increasingly seek to roll back the Dodd-Frank financial-regulation law.

Obama included the message in his State of the Union speech Tuesday after the House of Representatives approved a measure last week that would loosen some restrictions in the 2010 law. His remarks also come as Wall Street reemerges as a force in Washington, having successfully attached one of its top legislative goals to a government spending bill that lawmakers approved at the end of last year.
