Body cam video featuring the suspect who allegedly drove the wrong way down a highway right past Kamala Harris‘ motorcade last month in Wisconsin has been released … and, cops say he was 3 times over the legal alcohol limit.

The Milwaukee County Sheriff’s Department released the clip from Monday, October 21 … showing the suspect, identified by authorities as Wayne Wacker, pulled over to the side of the highway after passing the VP’s motorcade.

We’ve shown you the clip … the suspect drives slowly down the highway — straight past Harris’ protection detail, causing alarm among the Secret Service agents protecting her.

In the video, obtained by WTMJ-TV, officers ask Wacker where he’s coming from … and, he responds he’s got no idea, while searching for close to 10 minutes for his ID What appears to be a can of beer is seen in his vehicle … though Wacker claims he only had a couple beers.

After some regular questions from the cops, Secret Service agents ask Wayne if he’s part of any extremist groups — which WW quickly shoots down.

Wayne then tries some field sobriety tests … failing pretty much all of them, it appears, seeming like he’s laughing through the incident.

Wacker also takes a breathalyzer test … and, cops in the clip say he’s well over the legal limit — registering a .252 BAC.

As we told you … cops at the time told us a 55-year-old man was suspected of drunk driving after an open beer can was allegedly found in his car. This man — now identified as Wacker — was arrested for drunk driving and second-degree recklessly endangering safety.
