奥巴马：美国从不拖欠债务

President Barack Obama tried to reassure the world Tuesday that the United States has always paid its bills, as the country faces a deadline to raise the debt ceiling.

Mr. Obama told journalists Tuesday that remarks from Congress indicating a debt default may not damage the world economic recovery make investors nervous. He called on Congress to hold a clean vote on raising the debt ceiling -- a vote with no other issues attached.

Mr. Obama also appealed to Congress to pass a clean spending bill and reopen the government -- now in its second week of a shutdown.

Republican House Speaker John Boehner said he is disappointed the president is refusing to negotiate on the debt limit or a spending bill. He said this is not the American system of government.

Boehner said the debt limit has always been fair game for bargaining, and he said the United States cannot keep spending money it does not have.
