"[Washington's] big fear is what would happen that, once in government, you would have a party at war with itself," Larson said, adding that the only fatal threat to the United States is "a party within the government at war with its own government.

"We have that in Washington today," he said. "We have the Tea Party. A lot of decent people, but at war with their own government."

Larson also said Tea Party Republicans "don't have a complete understanding of what they're doing" to the political system, and are being "manipulated by outside sources."
