Trump’s Bemidji rally took place in an airport hanger. According to a CNN producer who attended the event, at least 2,000 people were in attendance. Based on contact tracing by the state Department of Health, at least 16 cases, including two hospitalizations, were identified among attendees.

In the month preceding the rally, the seven-day average of new cases in Beltrami County, where Bemidji is located, was 2.85 new cases a day, according to Johns Hopkins University. On the day of the rally it had climbed up slightly to 3 new cases a day. But four weeks after, the average rate of new cases in the county had increased more than fourfold, reaching an average of 14.57 new cases a day.

On September 24, Pence and the President’s daughter, Ivanka Trump, held a “Cops for Trump” listening event indoors at the InterContinental Hotel in Minneapolis-St. Paul. The state Department of Health has found three event attendees with Covid-19 infections.
