Washington (CNN) - Sen. Saxby Chambliss says the U.S. debt is "one of the most dangerous threats confronting America."
The Georgia Republican made his comment in this week's Republican address, and come on the same day that, in the presidential radio and internet address, President Obama criticized Senate Republicans for their attempts to delay the extension of unemployment benefits and tax credits to people and small businesses hurt by the recession.
Republican leaders objected to the measure because it would have added to the national debt. They offered alternative bills that would have paid for unemployment benefits with unused stimulus funds.
While never referring explicitly to the legislative battle over unemployment benefits, Chambliss hammers home the GOP perspective.
"[O]ne of the most dangerous threats confronting America today doesn't come from without, but from within. And I'm talking about our national debt," Chambliss says.
"At a time when many Americans are clipping coupons and pinching pennies, President Obama and the Democrats in Congress continue to spend money that they – we – do not have."
Chambliss also links the growing debt with national security, noting that China holds a substantial amount of U.S. debt.
"Just as with our energy and food supplies, America is vulnerable when we disproportionately rely on other nations. It is a matter of great concern that we are in deep debt to countries that often don't share our values or positions," Chambliss says.
