Sparks flew at a congressional hearing Wednesday when International Brotherhood of Teamsters president Sean O'Brien told Republican Sen. Markwayne Mullin of Oklahoma—a multimillionaire whose family previously owned five non-union plumbing companies—that "we hold greedy CEOs like yourself accountable."
The exchange happened during a hearing convened by Sen. Bernie Sanders of Vermont—chair of the Senate Committee on Health, Education, Labor, and Pensions—titled "Defending the Right of Workers to Organize Unions Free from Illegal Corporate Union-Busting."
