I disagree.... As long as they are employees, they are required to submit to investigations and such.  These people need to be PROSECUTED not just simply fired.    Once prosecuted, they all must be banned from governmental service for life. CDC must be getting way too much funding if they can devote resources to something like this in the middle of a pandemic....    The organization making these trainings/resources available also needs to be banned from governmental contracts.  All employees of this organization should be banned as well.
