Who said what: The Presidential debate's best quotes

In a passionate debate with tensions running high, here are some of the key quotes from Donald Trump and Hillary Clinton.

:: "This was locker room talk. I'm not proud of it. I've apologised to my family. I've apologised to the American people." - Mr Trump on the comments he made about women in a 2005 recording.

:: "I have great respect for women. Nobody has more respect for women than I do." - Mr Trump.

:: "What we all saw and heard on Friday was Donald talking about women, what he thinks about women, what he does to women, and he has said that the video doesn't represent who he is, but I think it's clear to anyone who heard it that it represents exactly who he is, because we've seen this through the campaign. We've seen him insult women, we've seen him rate women on their appearance, ranking them from one to 10, we've seen him embarrass women on TV and on Twitter. We saw him after the first debate spend nearly a week denigrating a former Miss Universe, in the harshest most personal terms. So yes this is who Donald Trump is." - Mrs Clinton commenting on the controversial tape recording.

:: "I want to send a message, we all should, to every boy and girl, and indeed to the entire world, that America already is great, but we are great because we are good, and we will respect one another, and we will work with one another, and we will celebrate our diversity. These are very important values to me, because this is the America that I know and love, and I can pledge to you tonight that this is the America that I will serve if I'm so fortunate enough to become your president." - Mrs Clinton's message to the world.

:: "It's just words folks, it's just words." - Mr Trump's reaction to Mrs Clinton's message.

:: "What he's done to women, there's never been anybody in the history of politics in this nation that's been so abusive to women." - Mr Trump referring to Bill Clinton.

:: "When I hear something like that I am reminded of what my friend Michelle Obama advised us all: 'When they go low you go high.' Look, if this were just about one video maybe what he's saying tonight would be understandable, but everyone can draw their own conclusions at this point about whether or not the man in the video or the man on the stage respects women. But he never apologises for anything to anyone." - Mrs Clinton on taking inspiration from first lady Michelle Obama

:: "I hate to say it but if I win I'm going to instruct my attorney general to get a special prosecutor to look into your situation. There has never been so many lies, so much deception. You ought to be ashamed of yourself," Mr Trump said, and in response, Mrs Clinton said: "It's just awfully good that someone with the temperament of Donald Trump is not in charge of the law in this country." Mr Trump replied: "Because you'd be in jail."

:: "I respect his children. His children are incredibly able and I think that says a lot about Donald." - Mrs Clinton on what she respects about Mr Trump.

:: "I will say this about Hillary - she doesn't quit, she doesn't give up. I tell it like it is. She's a fighter." - Mr Trump on what he respects about Mrs Clinton.
