The bus, featuring slogans on the back such as "Follow Me to Mexico" and "Danger!"
The Deportation Bus Tour is not Williams' first time in the spotlight.
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".
"If you are as exhausted as I am by politicians who do nothing but talk, and you want to see this bus filled with illegals, vote Michael Williams on May 22", said Williams said in a campaign ad released in advance of the bus tour.

A number of local governments in Georgia already participate in the program.
In his profile on Facebook - in which he describes himself as "a fearless conservative" - his campaign has put a statement explaining that his journey will start on Wednesday, May 16 and will visit "each of the most risky sanctuary cities of Georgia", including Clarkston, Decatur, and Athens. "Murderers, Rapists, Kidnappers, Child Molestors, and Other Criminals on Board", is the latest move by Republican candidates to take a hard line on illegal immigration, using rhetoric similar to President Trump's. Supporters argue they protect the rights of residents who are valuable contributors to a community. Proponents say that local cooperation with federal immigration officials promotes public safety, thwarts national security threats, and is essential to upholding the rule of law in the US.
That didn't stop the ad from sparking a backlash from some groups as images of the bus spread online. "We're going to put them on this bus and send them home", said Williams.
Law&Crime has reached out to Williams for comment about the bus, but he has yet to respond.
In the official press release, Williams' campaign says he is "the most outspoken anti-illegal candidate in Georgia's history".
Secretary of State Brian Kemp recently released a commercial in which he tells voters that his pickup truck might come in handy.
