Donald Trump is apparently employing a scorched-earth policy in the second presidential debate Sunday night, if a pre-debate Facebook Live video is any indication.

In the video, which Trump billed as a glimpse into the final stages of his debate prep, the GOP presidential nominee is joined by three of Bill Clinton's most prominent accusers: Paula Jones, Juanita Broaddrick and Kathleen Willey. Also appearing is Kathy Shelton, who argues that Hillary Clinton as an attorney in the 1970s attacked her credibility while representing a man she says raped her.

Join me in St. Louis, Missouri - as I conclude my debate prep.

Introducing the group as “four courageous women," Trump then allowed each of the women to deliver brief remarks.

Jones, who sued Bill Clinton, alleging he sexually harassed her while Arkansas governor, said she was there because Trump is “going to make America great again.”

Broaddrick, who alleges Clinton sexually assaulted her in the 1970s, was more pointed: “Mr. Trump may have said some bad words, but Bill Clinton raped me, and Hillary Clinton threatened me. I don’t think there’s any comparison."

Broaddrick's accusations have never been proven.

The appearances by the Clinton accusers come as Trump's campaign is in turmoil following the Friday release of a recording from 2005 in which he is heard graphically discussing groping women.

In response to the Trump pre-debate event, Clinton communications director Jennifer Palmieri said their campaign was "not surprised to see Donald Trump continue his destructive race to the bottom."

Palmieri added: "Hillary Clinton understands the opportunity in this town hall is to talk to voters on stage and in the audience about the issues that matter to them, and this stunt doesn’t change that. If Donald Trump doesn’t see that, that’s his loss. As always, she’s prepared to handle whatever Donald Trump throws her way."
