Sent there for his own safety, huh? I get the impression the government wants Chauvin gone if that is keeping him safe sort of like Epstein. 
With the real information on George Floyd's death, and he cowardice of everyone from Mayors and governors to the Courts pandering to the lynch mob and the domestic terrorism that resulted from the bullshit narrative, you can bet your bottom dollar they want Chauvin eliminated.
IMHO, this is just further cowardice on the part of those who railroaded him and permitted, if not encouraged the billions of dollars in damages that resulted from the incorrect narrative promoted by politicians and the press to placate violent Marxists hell-bent on massive looting and destruction.
