South Dakota Gov. Kristi Noem (R) recalled in her newly released controversial memoir how a mistake in 2016 saw her come very close to causing a massive tragedy on the road.

In excerpts from her memoir, No Going Back, that were published by The Daily Beast on Thursday, Noem admitted she once made the mistake of failing to personally check the hitch between the pickup truck and flatbed trailer she was going to drive.

The then-congresswoman was driving at 70 miles per hour on a crowded eight-lane interstate outside Nashville with her daughter Kass when we hit a bump, and the trailer came unhitched.
