ST. PAUL, Minn. - U.S. Rep. Steve King, R-Iowa, said Thursday that Democratic presidential candidate Barack Obama's upbringing was devoid of patriotism or the principles that make the United States a great country.

King, who represents western Iowa and is known for making provocative statements, made a speech here asking the Iowa GOP delegation what part of Obama's upbringing, relationships and education would be appropriate for someone who wanted to be president.

"There is no part of that that I would subject a child, a young man or woman to. I don't think that there's a nurture there that shows a thread of patriotism or a sense of appreciation of free market capitalism or the destiny of America or what has made this country great," he said.

Republicans have been increasingly questioning Obama's patriotism.

King also criticized Obama for not putting his hand over his heart in 2007 when the National Anthem was played at Sen. Tom Harkin's annual Steak Fry fundraiser. He said that stemmed from his nurturing, too.

Obama, whose grandfather was a World War II veteran, has said he was taught that you stand at attention during the National Anthem and put your hand over your heart during the Pledge of Allegiance.

Obama spokesperson Jenni Lee called King's claim "ridiculous."

"As opposed to offering any real solutions to fix our economy or get working families affordable health care, the Republicans are resorting to Washington-style name calling and personal attacks," she said.
