Dale Shull sent a message to Mary Barra that said:
If you assisted GM in NOT supporting the production of ventilators you need to IMMEIATELY resign. This is absolutely totally inappropriate behavior. Especially since without the bail out in 2008-2009 GM would NOT exist. Some payback. You need to be ashamed of yourself. AND if for some reason you did not slow down the production of the ventilators you need to determine who within GM did and eliminate their jobs.
