Graham said there were more economic ideas to come from McCain.

(CNN) - McCain surrogate Lindsey Graham said Sunday that the Republican nominee will unveil new proposals to "jump-start the nation's economy" over the final three weeks of the presidential campaign.

"I think it goes along the lines of, now's the time to lower tax rates for investors, capital gains tax, dividend tax rates, to make sure that we can get the economy jump-started," the South Carolina senator said on CBS's Face the Nation.

John McCain has already laid out a plan to buy $300 billion in troubled mortgages, and re-negotiate the terms directly with homeowners. On Friday, he endorsed the idea of suspending the current requirement that seniors start drawing down their IRAs and 401Ks once they reach age 70-and-a-half.

Graham said the proposals would form a "very comprehensive approach to jump-start the economy by allowing capital to be formed easier in America by lowering taxes" - but would not include any plans for further bailout funding.
