"Hillary Clinton apparently thinks this is an episode of 'Shark Tank,' but this is America," Pence said.
 
"It's serious business."

Pence said Trump's tweet about bringing Flowers to the debate was "really mocking the fact that Hillary Clinton was trying to distract attention away from this moment in our national life where the American people are going to see a strong contrast between" both candidates.

Trump tweeted on Saturday that if "dopey Mark Cuban of failed Benefactor fame wants to sit in the front row, perhaps I will put Gennifer Flowers right alongside of him!"

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

Trump was responding to billionaire Cuban, who last week said he accepted an invitation from Clinton to sit in the front row at Monday's debate.

Flowers appeared to accept Trump's invitation on Saturday.

"Hi Donald. You know I'm in your corner and will definitely be at the debate!..." she tweeted.
