Top Senate Democrats are trying to strip the health insurance industry of its protection from federal anti-trust laws.
If enacted, it would mean more federal regulation of the industry.
"Why are our insurance companies exempt from antitrust laws?" said Rep. Diana DeGette, D-Colo., a lead co-sponsor of the bill. "There are only two industries with that exemption: insurance and Major League Baseball. If it ever had a rationale, it's no longer operative."
The move comes as the insurance companies have stepped up their criticism of the Democrats' health care reform plans.
Health insurance companies are saying they're already one of the most regulated industries in the country.
Meanwhile, the health care measure passed by the Senate Finance Committee has finally been made public, coming in at a massive 1,500 pages.
