Arianna appeared on MSNBC's 'Morning Joe' alongside Massachusetts senate candidate Elizabeth Warren, to discuss JPMorgan CEO Jamie Dimon's appearance before a senate committee Wednesday.
Arianna asked Warren: "What is the most important connection between what JPMorgan did, and what's happening to middle class families across America?"
Warren responded: "It was the deregulation of the financial services industry that broke the consumer credit market and put families at risk."
When questioned by another panelist on how she would create jobs, Warren urged the passing of a jobs bill that would put people to work repairing and upgrading America's infrastructure.
In addition to infrastructure investment Warren advocated investment in education and medical research.
