His campaign released a statement Thursday calling the housing crisis a "complex problem that deserves a careful, balanced approach that helps the homeowners in trouble, not big banks and speculators that acted irresponsibly."

"However, what is not necessary is a multibillion dollar bailout for big banks and speculators, as Sens. Clinton and Obama have proposed. There is a tendency for liberals to seek big government programs that sock it to American taxpayers while failing to solve the very real problems we face," it said.

Clinton's campaign also accused Obama of copying her plan, calling for an additional stimulus package one week after Clinton did.

But Obama's senior economic adviser Daniel Tarullo said Obama has laid out a plan for financial regulation that is more comprehensive than any other candidate.

Polls show that the economic slowdown caused by the credit crunch has become a top concern for US voters.
