(CNN) It's the kind of message you don't expect to see on a US election campaign bus: "FOLLOW ME TO MEXICO."

Those are the words on the back door of a repainted school bus Michael Williams is using to drum up support in his bid for the Georgia governor's seat. He's dubbed it the "Deportation Bus" and says it's a show of support for the Trump administration's crackdown on illegal immigration.

In a press release Tuesday, Williams said his message is simple: shining a light on what he claims are "the dangers of sanctuary cities and the overwhelming problem of illegal immigration."

In a campaign ad and a press release unveiling the bus, Williams said he aims to have every city in Georgia participate in 287(g), the federal program that allows local police and sheriffs to cooperate with the feds on immigration enforcement.

"We are going to implement my 287(g) deportation plan. That's going to fill this bus with illegals, to send them back to where they came from." Williams says.
