King said Democrats' health care legislation, signed into law last year by President Obama, ushered in the “the unconstitutional taking of American liberty.”

"The most sovereign thing we have is our soul,” said King. “The second-most sovereign thing we have is our skin."

King, who could face a tough reelection fight next year due to redistricting, also called on Iowans to help defeat President Obama in the presidential elections.

“The function of government is to preserve and secure your rights,” said King. “We need to elect a full-spectrum conservative for president — and it isn’t President Obama."
