Amazon picks Twitter fight with Bernie Sanders and Elizabeth Warren amid union campaign

Amazon is going on the offensive against prominent lawmakers amid the most significant union campaign in the history of the online retailer. On Friday, Amazon's official PR Twitter account, @amazonnews, slammed senators Bernie Sanders and Elizabeth Warren for their ongoing criticism of the ecommerce company.

"There's a big difference between talk and action," Amazon tweeted. "@SenSanders has been a powerful politician in Vermont for 30 years and their min wage is still $11.75. Amazon's is $15, plus great health care from day one. Sanders would rather talk in Alabama than act in Vermont." Amazon also retweeted a comment by Dave Clark, the company's worldwide consumer CEO, who said Sanders "should save his finger wagging lecture until after he actually delivers in his own backyard."
