For the last three and a half years, Cass Sunstein has helped drive a series of historic accomplishments on behalf of the American people. From putting in place lifesaving protections for America's families, to eliminating tens of millions of hours of paperwork burdens for our nation's citizens and businesses, Cass has shown that it is possible to support economic growth without sacrificing health, safety, and the environment. Cass has shepherded our review of existing rules to get rid of those that cost too much or no longer make sense, an effort that is already on track to save billions of dollars. With these reforms and his tenacious promotion of cost-benefit analysis, his efforts will benefit Americans for years to come. I can't thank him enough for his friendship and for his years of exceptional service.
