WASHINGTON (Reuters) - Amazon.com's social media team bared its teeth this week to go after two big critics in Congress: Senators Bernie Sanders and Elizabeth Warren.

Amazon first struck out Wednesday with tweets by Dave Clark, chief executive of Amazon's worldwide consumer business, who criticized Sanders for pushing for a $15 minimum wage and supporting Amazon workers in Alabama who are considering unionizing.
