Senator McCain expressed confidence today that Congress and the Bush administration can reach consensus before markets open Monday on a $700 billion bailout plan to rescue financial institutions from crippling debt.

His Democratic rival, Senator Obama, also called for prompt bipartisan action.

Mr. McCain, the Republican presidential candidate, told the Clinton Global Initiative in New York that it’s often difficult to act quickly and wisely. But he said that is what’s required now to come up with a plan that can achieve bipartisan support in the House and Senate.

“Time is short and doing nothing is not an option,” Mr. McCain said. He headed to Washington after his speech.

Mr. Obama, speaking to the same audience by satellite later in the morning, agreed that it was imperative to act quickly in a bipartisan manner.

“Now is the time to come together, Democrats and Republicans, in the spirit of cooperation on behalf of the American people,” Mr. Obama said.

But Mr. Obama made clear that his schedule this week included the first presidential debate. He said he would be in Mississippi tomorrow for the debate with Mr. McCain after joining legislators in Washington today. Mr. McCain has called for postponing the debate, set to be on foreign policy issues, if no deal has been reached on the bailout by then.

Both presidential candidates received high praise from President Clinton.

Mr. Clinton praised Mr. McCain on the environment: “When most people in his party had been thinking that global warming was overstated … he decided to look into it.”

In lauding Mr. Obama, Mr. Clinton referred to a conversation the two men had earlier this month at Mr. Clinton’s Harlem office.

“Eighty percent of the conversation had nothing to do with politics and everything to do with the responsibilities of the next president for the welfare of the American people and the future of the world,” Mr. Clinton said.

The candidates were equally gracious to Mr. Clinton, thanking him for his work with the initiative.
