I read that she bought DuPont, but I can't confirm that DuPont makes body bags. As much as I despise her, we need to be accurate about this stuff to ward off the "fake news" tag.
I was told this by a friend and assumed it was common knowledge. Now that's it's going a bit 'viral' I'm wondering if it's not common knowledge. I don't know how to check how true.
From my understanding, they don't directly manufactur body bags but their products are being used for other companies to create body bags. A quick Google search showed Respirex uses their product to make their body bags.
