Obama's Regulation Czar to Resign

Cass Sunstein heads back to Harvard Law School

Cass Sunstein, the chief regulator for President Barack Obama, said today he will resign, leaving behind a record criticized by both political opponents and White House allies.

Sunstein, 57, will leave the White House Office of Information and Regulatory Affairs, which oversees federal rules, later this month and return to Harvard Law School.

At the federal agency, Sunstein pushed agencies to weed out unnecessary or outdated regulations and ordered them to consider the cumulative financial burdens of rulemaking when crafting new directives.
