The last question of today's second US presidential debate was absolutely perfect. It was also probably the hardest one they faced in the whole debate.

"Would either of you name one positive thing that you respect in one another?" the audience member asked, drawing laughter and applause from the rest of the crowd. Clinton answered first.

"I think that's a very fair and important question. I respect his children. His children are incredibly able and devoted and I think that says a lot about Donald," she said.

"I consider her statement about my children to be a very nice compliment," Trump responded.

"I will say this about Hillary. She doesn't quit, she doesn't give up. I respect that.

"She does fight hard and she doesn't quit and she doesn't give up and I consider that to be a very good trait."

Trump says Hillary would be in jail if he was President

Clinton and Trump shook hands after the debate ended, something they refused to do 90 minutes earlier.

The debate was especially icy at the outset, replete with talk of sexual impropriety and Trump threatening to jail Clinton over her erased emails.

But the St. Louis rumble concluded with a voter asking them to say something nice about each other.

Clinton's and Trump's families quickly joined them on stage as the debate wrapped up.

The candidates greeted their relatives and then circulated the room, which is filled with undecided Missouri voters as well as supporters of the two campaigns.

Clinton said she felt great after her debate with Trump.

But she says she was "surprised by the absolute avalanche of falsehoods" he spoke during the 90-minute showdown.

She spoke briefly to reporters aboard her campaign plane for the flight from St. Louis to White Plains, New York.

Former President Bill Clinton was aboard for the first time.

Clinton says she was aware that Trump stood very close to her as she answered some questions.

She says it was a "very small space," but that Trump was "very present."
