Billboard warns Trump's Iowa rally will be "superspreader event"

National agricultural advocacy group Rural America 2020 began displaying a digital billboard outside of the Des Moines International Airport in Iowa on Tuesday ahead of President Trump’s Wednesday rally, warning residents that it will be a “COVID superspreader event.”

The group on Tuesday tweeted an image of the billboard, which says “TRUMP COVID SUPERSPREADER EVENT,” along with a large arrow pointed toward the airport where the president will speak to supporters.
