"Hi Donald. You know I'm in your corner and will definitely be at the debate!” read a tweet from what appears to be Flowers's account.

In a tweet earlier Saturday, Trump, the Republican nominee, offered to bring Flowers to the debate in response to the attendance of billionaire Clinton supporter Mark Cuban. Cuban said on Thursday that he accepted an invitation from Clinton to sit in the front row at Monday’s presidential debate.

“If dopey Mark Cuban of failed Benefactor fame wants to sit in the front row, perhaps I will put Jennifer Flowers right alongside of him!” Trump initially tweeted before deleting the tweet and reposting it with the correct spelling of Flowers's first name. 

Bill Clinton testified under oath in 1998 that he had a sexual affair with Flowers. 

Flowers's assistant, Judy Stell, confirmed to BuzzFeed News that she would attend. 

"Ms. Flowers has agreed to join Donald at the debate,” she said.
