The campaign’s plan, which was closely held and unknown to several of Trump’s top aides, was thwarted just minutes before it could be executed when officials with the Commission on Presidential Debates intervened. The commission officials warned that, if the Trump campaign tried to seat the accusers in the elevated family box, security officers would remove the women, according to the people involved, who spoke on the condition of anonymity because the discussions were confidential.

The gambit to give Bill Clinton’s accusers prime seats was devised by Trump campaign chief executive Stephen K. Bannon and Jared Kushner, the candidate’s son-in-law, and approved personally by Trump. The four women — three of whom have alleged Bill Clinton sexually assaulted or harassed them years ago — were to walk in the debate hall at the same time as the 42nd president and confront him in front of a national television audience.

“We were going to put the four women in the VIP box,” said former New York mayor Rudy Giuliani, who represents Trump in debate negotiations. “We had it all set. We wanted to have them shake hands with Bill, to see if Bill would shake hands with them.”
