Donald Trump says he feels guilty for never serving in the Vietnam War because he knows many brave people who did.
Trump's comments came during a Tuesday night event in New Hampshire that offered a more intimate exchange than his typical rallies. He opened the floor for questions and at times kept the audience near silence as he discussed where his patriotism comes from and what advice he'd give to young people.
He says politicians today need to use more "tough talk" when it comes to dealing with the Islamic State in the Middle East, and criticizes rivals for saying his tone is too brash.
He's also offering a warning to young people about the dangers of alcohol and drugs, saying they can hamper future success.
