Sen. Bernie Sanders, I–Vt., on Thursday challenged the bosses of four American companies to come Washington, D.C., to face their employees in a livestreamed town hall on July 16, during which they would be prompted to justify how much they are paid.

“I really hope [the CEOs] have the guts to sit on a panel with their own employees and explain why it’s acceptable that they receive huge compensation packages while their very own workers are struggling to put food on the table,” Sanders said in an interview Wednesday, according to CNN. “I hope they have the courage to do so. The invitation is sincere.”
