**St. Louis** Democrat Hillary Clinton and Republican Donald Trump began their second presidential debate here on Sunday night.
The two presidential candidates will go head to head for 90 minutes at the Washington University in St. Louis, Missouri, US, CNN reported.
This is second of the three presidential debates.
Moderator Meghan Keneally of ABC News along with CNN’s Anderson Cooper, opened the 90-minute debate at the Washington University here in the US with the first question coming from a teacher to Clinton.
The first question was if Clinton is modelling appropriate and positive behaviour for young people.
“It is very important for us to make clear to our children that our country really is great,” Clinton answered.
She added that she wants Americans “to respect one another” and “lift each other up” as well as look for ways to celebrate our diversity.
“We are going to respect one another, lift each other up. I will work for every American. I want to heal our country and bring it together,” she said.
Clinton is the first woman to represent a major US party in the presidential race.
Among the audience, the nominees’ families are present including Hillary’s husband and former US President Bill Clinton and Trump’s wife Melania.
Two minutes will be allotted to answer a question asked by the moderators and the audience.
CNN’s Anderson Cooper asked Trump about the sex boast tape to which the New York billionaire responded: “This was locker-room talk… I am certainly not proud of it.”
“I’ve said things that I was embarrassed by it. I have tremendous respect for women and women have tremendous respect for me,” he added.
Trump dismissed Cooper’s assertion that he bragged about sexual assault in the 2005 leaked tape in which he made lewd comments about women.
He said: “No I didn’t say that at all. I don’t think you understood what was said. I apologised to my family. I apologised to the American people. Certainly I’m not proud of it.”
According to BBC, he tried to change the subject to the Islamic State militant group.
