Seems to me all Dr. Fauci is saying is that it's still too risky to be in a crowd of strangers, especially if you aren't going to take precautions like wearing a mask, social distancing or washing your hands frequently.  I don't see any political motives here t all.  
I myself think these rallies are a bad idea. but what do I know?  I will be curious to see the tally of new cases and -- God forbid -- any deaths in these cities like Tulsa after the rallies are held.  Of course, with all the fudging of numbers going on, any reported increases might be suspect.
