I suspect the firing would happen either way, but the difference would be in how the company handled it. Delete the tweets and the person gets a severance, maybe a "layoff" instead of firing with cause, and no pushback on unemployment claims. Don't delete it, fired with cause, no severance, no unemployment, potential criminal charges. It looks like the tweets are gone now anyway.
