Watch Obama say debate shouldn't be postponed » McCain's suspension of his campaign hours before Bush's address to the nation on the troubled state of the U.S. financial system, a problem for which Bush's administration has proposed having the Treasury Department buy up to $700 billion in firms' troubled assets -- mainly mortgage-backed securities -- whose values declined as the housing market imploded. The plan's goal is to stabilize the companies and prompt them to lend again. Watch Bush's address » While McCain and Obama jointly called for bipartisan cooperation on the economic crisis, in a separate statement Obama outlined some principles he said should guide the legislation and called on McCain to support them. Obama said the plan should help the "millions of families facing foreclosure" and not just Wall Street; create "an independent, bipartisan board to ensure accountability and complete transparency"; have Wall Street repay taxpayers for the bailout; and have an independent, bipartisan board to oversee the bailout. "This plan cannot be a welfare program for CEOs whose greed and irresponsibility has contributed to this crisis," Obama's statement said. Before Bush invited McCain and Obama to the White House, Senate Majority Leader Harry Reid issued a statement saying that the presidential debate should go on. "If there were ever a time for both candidates to hold a debate before the American people about this serious challenge, it is now," he added. McCain senior adviser Mark Salter said that the campaign will suspend airing all ads and all campaign events pending Obama's agreement. Salter also said McCain called Bush and talked to colleagues in Washington and learned that passage of the bailout plan as it then stood was next to impossible. Between McCain's announcement and Bush's speech, congressional leaders said progress has been made in negotiations. "We agree that key changes should be made to the administration's initial proposal," House Speaker Nancy Pelosi and House Republican Leader John Boehner said in a joint statement. "It must include basic good-government principles, including rigorous and independent oversight, strong executive compensation standards, and protection for taxpayers."
