"In fact, I don’t know, other than the candidate, what kind of infrastructure, if anything, they have here, which is similar to what I hear from others around the country," Walker said.

Asked whether he would anticipate putting extra law enforcement in place for a Trump visit, Walker said the candidate would be given the same assistance as any other visiting the state.

"I think at this point, we’re just appreciative that Wisconsin's relevant in both primaries, both in the Republican and Democrat side," Walker said. "So I think on behalf of the voters here, we appreciate any of the candidates, be it Hillary Clinton or Bernie Sanders or be it Donald Trump, Ted Cruz or John Kasich coming to the state, and we want to make sure not only they, but the people both coming to support them and those that may be opposed to them, are all safe and sound."

Walker said he has no plans to attend a presidential campaign event unless and until he makes an endorsement, which would likely happen later next week.
