held a rally that was fined for breaking COVID-19 mandates?

The first rally Trump held since June, on September 13, 2020, was issued a $3,000. A compliance officer noted six violations by the indoor venue regarding state COVID-19 regulations, which mandated an attendance limit of 50, the wearing of masks, and the practice of social distancing. The venue issued temperature checks, had hand sanitizers available, and handed out face masks, though there was no requirement for the crowd to wear them.

On Twitter, Trump said that the state’s Governor tried to require an outdoor venue, before going on to claim that the Governor would assist in rigging the election.
