MacKenzie Bezos pledges half her fortune to charity after Amazon divorce

MacKenzie Bezos, the former wife of Amazon.com Inc Chief Executive Jeff Bezos, pledged on Tuesday to give away half her fortune to charity, following a movement founded by billionaires Warren Buffett and Bill and Melinda Gates. Bezos, whose former husband is the world's richest man, was one of 19 people on Tuesday to sign the "Giving Pledge," a campaign announced in 2010 by Berkshire Hathaway Inc's Buffett and Microsoft Corp co-founder Bill Gates. "In addition to whatever assets life has nurtured in me, I have a disproportionate amount of money to share," MacKenzie Bezos said in a statement.
