TOLEDO, Ohio – Senator Barack Obama on Tuesday voiced his support for the administration’s latest attempt to stabilize the financial markets by investing money into the American banking system, but said he was concerned the plan did not include provisions to limit the pay of business executives.

In his first comments on the historic government intervention, Mr. Obama said he believed the proposal offered a “promising” way to ease the credit crisis affecting Americans from all walks of life. But he said new regulatory requirements needed to accompany the infusions of cash into banks.

“If we’re just giving them money, but we’re not making sure that they are curbing some of the excessive risks that got us into the mess in the first place,” Mr. Obama told reporters, “then we are just continuing the same philosophy that has failed the American people so badly.”

Mr. Obama, who was sequestered at a resort near Lake Erie for the second day of preparations for his final debate with Senator John McCain on Wednesday, said he had spoken to Treasury Secretary Henry M. Paulson Jr. about the plan. But he said he wanted to review the detailed proposal before rendering a final judgment.

He said the limits on the so-called golden parachutes for chief executives, which he pushed to be a part of the first government bailout plan, remain a key point.

“I am concerned that the way that they structure this new mechanism that we are cracking down on excessive CEO pay –- that I think should be part of the deal,” Mr. Obama said. “And I’m also concerned that taxpayer shares -– that they are purchasing or they are receiving as a consequence of this injection of equity –- is a good deal for tax payers. I think that if tax payers investing in Goldman Sachs, they shouldn’t get a worse deal than when Warren Buffet invests in Goldman Sachs.”

Mr. Obama, one day after presenting new steps to address the economic crisis, offered a mix of tepid praise and criticism at the proposals that Mr. McCain announced Tuesday.

“There are some ideas that Senator McCain has put forward in the last couple of weeks that are very bad ideas,” Mr. Obama said. “The idea, for example, of purchasing homes at full price from banks, banks have no losses and tax payers automatically have losses, that’s a bad idea.”

He added, “He’s had some good ideas. I think the idea of making sure that people aren’t forced to sell their 401(k) or IRA accounts at the age of 70 when the market is in the tank, I think that makes sense and in fact I acknowledged that in my speech yesterday.”

Mr. Obama said he was not sure that Mr. McCain’s proposed reduction in the tax on long-term capital gains –- to 7.5 percent from 15 percent -– was particularly relevant because “nobody really has capital gains right now.”

“That,” he said, “probably is not going to be particularly useful in solving the financial crisis.”
