 Gratzer testified several times during the recent health-care reform debates, including before the House Budget and Ways and Means Committees.In a June 2009 U.S. Congressional hearing on the issue of single-payer health care, Gratzer and U.S. Rep. Dennis Kucinich (D-OH) clashed over Canadian healthcare statistics.According to a June 29, 2009 front-page article in Canada's "National Post", "armed with a stack of statistics about patient wait lists in Canada, and a fusillade of dire warnings about the life-threatening consequences of government-managed care," Gratzer "has emerged as the go-to expert witness for GOP lawmakers hoping to sow doubt in Congress about the wisdom of embracing Mr. Obama's call for a public health insurance option to compete with private insurers."
