Walsh, a former tea party congressman from Illinois who is now a conservative talk radio host, tweeted, "On November 8th, I'm voting for Trump. On November 9th, if Trump loses, I'm grabbing my musket. You in?"
Walsh did not immediately respond to a CNN request for comment. But he did respond to CNN's Jake Tapper via Twitter when he asked: "What exactly does that mean?"
"It means protesting. Participating in acts of civil disobedience. Doing what it takes to get our country back," he responded to Tapper.
