When looking at 3M don't just look at the current CEO, look at the previous, too. Inge Thulin. He has direct ties to Merck. Merck is a huge pharmaceutical company and major vaccine maker.

Also involved with PFAS and PFOA, I believe. Some of those "forever" chemicals.
Some screen grabs of my search on 3M settlement for chemical contamination in Minnesota.
