(WASHINGTON, AP) — President Barack Obama is warning congressional Republicans not to undo financial rules he signed two years ago and he’s taking specific note of the work of a consumer agency created by the new law.

In his Internet and radio address Saturday, Obama drew attention to the Consumer Financial Protection Bureau, noting that it and other regulators recently cracked down on three credit card companies, ordering them to pay $400 million to people who were misled into making purchases they didn’t want.

“Sadly, that hasn’t been enough to stop Republicans in Congress from fighting these reforms,” Obama said. “Backed by an army of financial industry lobbyists, they’ve been waging an all-out battle to delay, defund and dismantle these new rules.”

Obama often reminds campaign audiences of his push for new restrictions on Wall Street, changes that passed Congress despite widespread opposition from Republicans.

Obama, sounding much like a consumer advocate, also informed listeners that they can now contact the consumer bureau to seek redress over problems with credit scores.

In the Republican address, Missouri congressional candidate Ann Wagner promoted Mitt Romney for president, called for changing the U.S. tax code, which she called a “72,000-page monstrosity,” and urged the repeal of Obama’s health care law. Wagner is seeking a seat vacated by Republican Todd Akin, who is running for the Senate.

“He promised to listen, promised us change, but all we’ve gotten is more of the same,” she said of Obama. “More spending, more red tape, more debt and decline.”
