Galvin said he gently reminded the Clinton campaign what the rules are.

“So we are being very clear with local election officials irrespective of his status, he cannot go inside a polling place and approach voters,” Galvin said.

Galvin said there is a penalty, but they only take action in cases of “absolute disobedience.”

“He was a good president so we just want to make sure that he knows the rules,” Galvin said. “He’s not from here so he may not know.”
