Iowa Senator Chuck Grassley is refuting claims by the group “Iowans for Tax Relief” that he’s working with Democrats on a healthcare bill. Grassley says he’s there to ensure that the country doesn’t end up with a “government run” system. The New Hartford Republican says the country’s healthcare system does need some work, but feels congress could make it worse if they’re not careful. The “Iowans for Tax Relief” began circulating an email this week urging people to politely voice their concerns over the single payer system at Grassley’s town hall meetings. Meanwhile, a Democratic state lawmaker from eastern Iowa is calling on Grassley to dispel what he calls myths about the healthcare debate. Iowa City State Senator Joe Bolckom says Grassley should focus on healthcare consumer reforms.
