WASHINGTON: President Barack Obama said on Monday that Wall Street banks had failed to show remorse for the "wild risks" that triggered a financial meltdown and helped to push the United States into recession.

Obama unveiled a sweeping regulatory overhaul in June aimed at improving government oversight of banks and markets to avert a repeat of the financial crisis.

"The problem that I've seen, at least, is you don't get a sense that folks on Wall Street feel any remorse for taking all these risks," Obama said in an interview with PBS television.
