"At an October, 2015 Senate Energy Committee hearing, Bernie challenged Puerto Rican government leaders and U.S. Treasury Department officials to implement common sense solutions to help solve Puerto Ricos debt crisis. For instance, he urged the officials to transition away from expensive imported oil and toward clean and locally-produced electricity sources. Bernie also noted that Wall Street vulture funds knew they were making risky investments in Puerto Ricos debt that could only be repaid by exacerbating the misery of the Puerto Rican people and that it is only fair that they take a pretty significant haircut on their investments.
Shortly after, Bernie sent a letter to U.S. Secretary of Treasury Jack Lew urging the Obama Administration to convene a meeting with Puerto Rican leaders, its creditors, labor unions, business leaders, and pension advocates to work out a debt repayment plan that is fair to all sides."
