A CBS News affiliate reported Tuesday that a Hillary Clinton campaign bus may have illegally dumped "human waste" in a storm drain on the side of a road in Lawrenceville, Georgia.
Christian De La Rosa reported the dumping allegedly happened in between campaign stops in the battleground state and a HAZMAT team was called out to the area.
"Police tell me that when they showed up here to the 500 block of Grayson Highway, it was all covered in toilet paper and there was a foul smell," De La Rosa said.
Pictures obtained by the news station from an eye witness show the bus clearly marketed for the Clinton campaign and her efforts to have more people vote in the upcoming election.
Mark Robins said he saw wastewater dumping out of the bus and pouring out into the street and right over a storm drain. He added he captured pictures of the dumping on his cell phone.
"I don't care who you are. That's just wrong," Robins said.
De La Rosa said that investigators with the Georgia Environmental Protection Agency have concerns that the waste has now reached several bodies of water and are investigating the situation.
Mediaite reported that the DNC has issued an apology, calling the dumping an "honest mistake" and that they would be assisting in the investigation and a clean-up.
"This was an honest mistake and we apologize to the Lawrenceville community for any harm we may have caused. We were unaware of any possible violations and have already taken corrective action with the charter bus company to prevent this from happening again. Furthermore, the DNC will work with the Georgia Department of Natural Resources, as well as local and state officials to determine the best course of corrective action."
