Now that the summer is over and we’re just four months away from the Iowa caucuses, Donald Trump is going to have to actually explain how he plans to do all the things he has told us he wants to do. Trump started outlining his plans on CBS News’ 60 Minutes Sunday, although he still left details out.

The main point of his interview with Scott Pelley was an outline of his tax plan. He suggested that he will raise taxes on the rich, but proposes a “substantial reduction” for the middle class.

“It's a substantial reduction for the middle-income people. Because our middle class, Scott, is being absolutely decimated,” Trump said. “It will be a corporate also reduction, I think it'll be a great incentive for corporations.”

Trump suggested that he can make a part of the population exempt from income tax, despite the $19 trillion federal deficit. He said that he knows how to bring jobs back and is hoping to break the North American Free Trade Agreement, even if it is a law.

Elsewhere, Trump stood firm on his idea to build a wall along the Mexico-U.S. border to keep illegal immigrants out. He also wants to make sure that this wall actually looks good.

“ It will be a real wall. It'll be a wall that works,” Trump told Pelley. “It'll actually be a wall that will look good, believe it or not. 'Cause what they have now is a joke. They're-- they're ugly, little and don't work.”

As for the illegal immigrants who are already here, Trump wants to round them up “in a very humane way, in a very nice way.” Pelley told him that this didn’t sound practical, but Trump disagreed.

“It's going to work,” Trump said. “They have to come here legally. And you know, when I talk about the wall, and I said it before, we're going to have a tremendous, beautiful, wide-open door. Nice big door. We want people to come into the country.”

Later in the interview, Trump answered to the criticism that he can dish out insults but can’t take it when they are thrown at him.

“Oh I think I can take it. I could take it if it's fair,” he said. “Again, if people say things that are false which happens a lot with me-- if people say things that are false I will fight, like, harder than anybody. If I do something wrong, and that happens, and they write a fair story that I did something wrong, there's nothing to fight about. I can handle that. I don't like lying. You know, I'm a very honorable guy, I don't like lies.”
