Zuckerberg has also expressed his willingness to become more involved in the political sphere, hosting a re-election fundraiser with his wife PriscillaChan for New Jersey Governor Chris Christie in February.
Zuckerberg told ABC that he was motivated to add the organ donor tool in part because of discussions with his medical-student girlfriend, PriscillaChan, and also because he was moved by his friendship with the late Apple CEO Steve Jobs, whose life was extended by a liver transplant.
