Tim Cook Meets With Speaker of the House John Boehner
Tim Cook met with Speaker of the House John Boehner (R-OH) today. It is unknown what the topic of discussion was, but it's possible that Cook was lobbying Boehner to pass a tax holiday that would allow Apple and other companies with large overseas tax holdings to bring back their earnings at a lower corporate tax rate.
As of its most recent earnings call, Apple held $74 billion of its $110 billion in cash and marketable securities offshore.
