Icahn Wants to Upend Washington With $150 Million Super-PAC

Carl Icahn, the billionaire investor known for picking fights with corporate executives, is now aiming his financial might at members of Congress who he says aren’t willing to cut deals on pressing issues such as tax policy.

Icahn said he plans to put $150 million into a new super-PAC that would push for changes to the way U.S. corporations are taxed on their earnings abroad. But in a letter to Congressional leaders, he also suggested the group may take on other fights, raising the prospect of a potent new factor in the struggle between the moderate and conservative wings of the Republican party.
