Obama on Wednesday lashed out at the Bush administration and his opponent on the handling of the crisis on Wall Street as well as the $700 billion bailout plan by Treasury Secretary Hank Paulson.

Congress and the White House are trying to negotiate the details of what would be the most sweeping economic intervention by the government since the Great Depression. Bush has asked Congress to act quickly on the bailout proposal following news of failing financial institutions and frozen credit markets.

"The clock is ticking on this crisis. We have to act swiftly, but we also have to get it right," Obama said in Dunedin, Florida. "And that means everyone -- Republicans and Democrats, and the White House and Congress -- must work together to come up with a solution that protects American taxpayers and our economy without rewarding those whose greed helped get us into this problem in the first place."

Obama said it's unacceptable to expect the American people to "hand this administration or any administration a $700 billion check with no conditions and no oversight when a lack of oversight in Washington and on Wall Street is exactly what got us into this mess."

He said struggling homeowners must be taken care of in any economic recovery plan -- and that taxpayers should "not be spending one dime to reward the same Wall Street CEOs whose greed and irresponsibility got us into this mess." Read more on both candidates' recovery plans

He also hit McCain for switching from his stance as an advocate for market deregulation to a strong supporter of regulation since the Wall Street crisis became front-page news.

"He's suddenly a hard-charging populist," Obama said. "And that's all well and good, but I sure wish he was talking the same way over a year ago, when I introduced a bill that would've helped stop the multimillion-dollar bonus packages that CEOs grab on their way out the door."
