The war against agricultural company Monsanto and its popular weedkiller Roundup is just beginning, say attorneys for Dwayne “Lee” Johnson, the former school groundskeeper who was awarded $289 million in damages after the product caused his terminal cancer.

In their first joint appearance since the verdict, lawyers Robert F. Kennedy, Jr., and Brent Wisner shared information and incriminating internal emails from their court case on the fact-based weekly online news program “The HighWire with Del Bigtree.”

Wisner divulged that because of the expediency of the case–Johnson has only a few months to live–“only 10% of what we’ve got” has been brought to light.

“We’ve got hundreds of documents, far more damning than these, showing absolutely definitive misconduct” of Monsanto hiding Roundup’s risk to the public, Wisner told Bigtree. “The longer this case goes on, the stronger it will get. If we won here, we’re going to win everywhere.”
