Stewart has been a vocal champion of the issue in recent years, appearing at multiple Capitol Hill rallies alongside veterans advocates to push for legislation to speed up the process. He dedicated the first episode of his new show to the topic, featuring interviews with veterans suffering from the health effects of their deployments and the sit-down in McDonough’s office to push for a quicker response from VA. “From what I’ve seen, [researchers] have done a ton of National Academy of Science studies, and people waive those all the time and say that no links have been established [between burn pits and vet’s illnesses],” Stewart told McDonough. “But unfortunately, those studies all say there is insufficient data, and that data is not going to be getting any better because it’s provided by the Defense Department. And if it’s insufficient in 2008, it’s going to be insufficient in 2020.”
