Will Trumps Rally in Phoenix at the Dream City Church result in a spike of COVID-19 infections?

Trump's rally on June 23 at the Dream City Church filled the church to its capacity of 3,000 people. News reports showed most not wearing masks which were required, (but not enforced), by a order issued by Phoenix's Democratic mayor.

Arizona is experiencing a spike in Coronavirus infections: some 12,897 new cases over the last 5 days (June 17-22). Arizona has a population of about 7,297,000. In a crowd of 3,000 we might then expect about 5 new infections. If more than 20 attendees come down with COVID-19 within 2-14 days, we can comfortably conclude that the rally was a foci of contagion.

This question will resolve positively if major news outlets or an Arizona Health Authority determines that more than 19 persons became infected by attending the rally at the Dream City Church.

If no such reporting comes out before August 15th, the question resolves negatively.

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
