Health care reform legislation being pushed through Congress represents the "biggest snatch of freedom and liberty" in U.S. history, Rush Limbaugh tells "Fox News Sunday" host Chris Wallace in an exclusive interview to air this Sunday.

The conservative radio talk show host blasted the Democrats' health care bills as a front that would steal money from American businesses and effect the partial takeover of the private sector.

"This is not about insuring the uninsured -- this is not about health care," Limbaugh told Fox News. "This is about stealing one-sixth of the U.S. private sector and putting it under the control of the federal government."

Limbaugh warned that the legislation currently being worked out in Congress would amount to massive encroachments on personal and private behavior, much of which would fall under the purview of the legislation.

"And when they get this health care bill -- if they do -- that's the easiest, fastest way for them to be able to regulate every aspect of human behavior, because it will all have some related cost to health care -- what you drive, what you eat, where you live, what you do -- and there will be penalties for violating regulation."

Limbaugh said these changes would have a drastic effect on the U.S.: "It's going to be the biggest snatch of freedom and liberty that has yet occurred in this country."

In the wide-ranging interview, Limbaugh also discusses President Obama and the administration's Afghanistan policy, of which he has been highly critical. Limbaugh also speaks of his own recent -- and unsuccessful -- attempt to become a part-owner of the St. Louis Rams.
