MILWAUKEE (CBS 58) -- A group called the League of Progressive Seniors held a protest outside Riverside High School in Milwaukee Thursday. 

They're upset about the legal challenge filed by republicans over the safer at home order.

"We are the most vulnerable subjects of this virus," said Dain Maddox. "And I think we have the most wisdom. Stop fighting the governor. Let's work with the governor. Let's listen to the health officials. Let's make certain it's safe before we start opening businesses."

They rallied at Riverside because that was one of the five polling places in Milwaukee for the April 7 election.

Milwaukee's health department revealed that seven cases of COVID-19 in the area may be related to that election.
