Hillary Clinton did try to play a role in promoting environmentally sound policies and advocating for women in management.
"We know we haven't gotten as far as we'd like to be advancing women in our company, but we're very conscious of it," Wal-Mart founder Sam Walton said at a 1987 meeting. "We've got a very strong-willed young 'un on our board now; her name is Hillary. And Hillary made it very plain to us yesterday that we need to do certain things to recognize, to train, to advance women in Wal-Mart."
Twenty years later, critics say Wal-Mart still lags in promoting women to top jobs. (ABC News)
