Sen. Jay Rockefeller (D-W.Va.) compared the behavior of health insurance companies to a shark attack during Thursday's White House health reform summit. 

Several Democratic lawmakers have taken digs at the insurance industry during the forum, saying they are responsible for gouging insurance premiums and denying coverage to people with preexisting conditions, among other complaints.

"The health insurance industry is the shark that sits right below the water and you don't see that shark until you feel the teeth of that shark," he said.

Rockefeller's argument is red meat for liberals who have cited health insurance abuse as a prime reason for reform. It also underscores the value of the summit for political theater.

The timing of the West Virginia senator's remarks is interesting considering he made them one day day after a killer whale attacked and killed its trainer at Sea World in Florida. 

Sen. Tom Harkin (D-Iowa) also made an eye-opening comment about health insurance reform, comparing it to racial desegregation.
