Peter Lee -- executive director of the California Health Benefit Exchange -- said the exchange will significantly expand health insurance coverage in the state, even if the U.S. Supreme Court strikes down the federal health reform law's individual mandate. Lee said the exchange "is going to have, we project, over two million people in it after a few years," which has "very little to do with the mandate." He said the exchange will aid residents because it is "a place where people can get subsidies for care, and can make informed choices."
