Protesters are already out in Janesville Monday night, ahead of a planned appearance by Donald Trump on Tuesday.
About sixty protesters have occupied the lobby of the hotel where he is staying and are staging a sit-in.
The Republican candidate has already had issues with rallies turning violent, as clashes between protesters and supporters break out.
So police in Northeast WI say they're working to ensure that doesn't happen, especially with at least one group already planning on protesting Trump's visit to Appleton.
Some of those protesters are coming together in Appleton tonight.
"People just started asking, 'what are we going to do? We need to do something,'" says Norys Piña, leader of Unidos por un Futuro Mejor Fox Cities.
With immigrant rights organization Voces de la Frontera planning protests over Trump's visit to Milwaukee tomorrow, Piña wants them to know they're not alone.
"We don't agree with Mr. Trump's platform on immigration," says Piña. "Here, in Wisconsin, immigrants are an essential part of the dairy industry, and we are workers, not criminals."
But Piña insists their intentions are peaceful, and that "we are not inciting any kind of violence."
However, Piña admits some protesters are concerned about ralliers turning violent.
"Yeah, there [are] some concerns," says Piña, "and I'm pretty sure we're going to get yelled at."
But when it comes to security, police say much of it is in the hands of the Secret Service, and FBI.
"If you show up a one of the rallies, or the events, be respectful," says Green Bay Police Capt. Paul Ebel, "everybody has their right to voice their opinions."
Ebel says he and others have been following the protests on national media to get a feel for what could happen.
"If we feel that there is a need to have extra officers on staff, we'll beef up our security," adds Ebel.
As for Unidos por un Futuro Mejor's protest, in Appleton, they intend to march from Houdini Plaza to the Radisson Paper Valley Hotel, where they say they will remain outside of Wednesday's event.
