The second-largest independent PR firm in the United States, APCO is known for its controversial use of front groups. APCO created front groups for Philip Morris to promote “tort reform” and downplay the science behind second-hand smoke. The firm later lent its expertise to protect the health insurance industry’s reputation — America’s Health Insurance Plans reportedly hired APCO to attack filmmaker Michael Moore’s 2007 documentary “Sicko” — and defend Kazakhstan’s president against allegations of abusive power.
