Billionaire investor Carl Icahn said Wednesday he is creating a $150 million super PAC focused on revising corporate tax law. Icahn will use his super PAC to press Congress to pass legislation that stops US companies from moving their profits overseas to take advantage of lower tax rates — a practice known as "inversions." American corporations—including Apple, one of his own biggest investments—are holding more than $2.2 trillion abroad, Icahn said. The investor laid out his plans in a letter posted on his website, which he said he also delivered to lawmakers. He said in a CNBC interview Wednesday that he's taking action because he's tired of Congress dodging the issue. "These guys are unwilling to compromise," he said of lawmakers. "They have to be held accountable."
Icahn said he will seek super PAC donations from others but noted in his letter that his own $150 million should be "more than enough to make voters fully aware of the horrible consequences" of inversions. He said it would take "a simple law" to address inversions and "It's ridiculous not to do it." Icahn joins other billionaires, including environmentalist Tom Steyer and gun-control advocate Michael Bloomberg, in using super PACs to tackle a single policy issue. Those two have spent tens of millions of dollars in recent elections boosting politicians who agree with their viewpoints on those topics and criticizing those who don't. Steyer and Bloomberg have seen limited success with their political projects. Icahn has not given details about how he'll use his super PAC. (Read more Carl Icahn stories.)
