Former Starbucks CEO denies union busting accusations by Bernie Sanders.

Starbucks' former CEO Howard Schultz denied breaking the law in response to criticism from Sen. Bernie Sanders, who accused the company of "the most aggressive and illegal union busting campaign in the modern history of our country." Schultz affirmed the right of workers to choose whether to unionize and defended the company's actions. More than a dozen decisions from federal officials have found that the company violated labor law in its response to a wave of union campaigns at its stores, according to the National Labor Relations Board, a federal agency.
