Sanders ardently opposed the trade deal that led to Panama Papers abuses; Clinton supported it
Bernie spoke out against tax havens & Panama Free Trade Agreement 5 years ago. Hillary was on the side of the rich

Then-Secretary of State Hillary Clinton and President Obama both supported the Bush administration-negotiated agreement, which ultimately made tax evasion an even larger problem. Progressive NGOs and watchdogs warned that this would happen at the time, but Clinton and Obama ignored them and strongly pushed for the deal.

Sanders, on the other hand, was one of the few voices to challenge the neoliberal trade deal.

Sanders began his statement on the Senate floor noting that Panama’s economy is incredibly small, with an economic output of just 0.2 percent of the U.S. economy’s. (Panama as a country, in fact, did not exist until the beginning of the 20th century, when the U.S. carved it off of Colombia and built an important canal there.)

“So I think no one is going to legitimately stand up here and say that trading with such a small country is going to significantly increase American jobs,” he explained.

The puts everything in a nutshell. All these trade agreements are bull. And Obama and Hillary Clinton have never seen one they didn't have to put into effect.
