WATCH: Asked about impeachment, Trump says he could have done 'very bad things' to Biden, Obama

You started telling midterm voters, the Democrats, they will impeach you. For what? They don't know because they were asked that question. The two — I saw two congressmen and a senator, so far, asked that question. They said, well, President Trump has created the greatest economy. When you see the real economy, what's happening with factories being built all over the country — it was — today it came out — there's never been a time like this, ever, where $21 trillion — that's even a lot of money for Brad and Michael and Susan. Twenty-one trillion dollars is being spent this year into our country. They said, so, President Trump has done a lot. You could add the eight wars to it. You could add the biggest tax cuts in history. All these things. What would you impeach him for? And all three didn't know. They said, we don't know. I don't know. One of them was just dumbfounded by the question. He said, yeah, we would impeach him. And what would you exactly impeach him for? Well, let's see. Let's think. That's it. So that's as far as he got. With that being said, I could have done very bad things to Hillary Clinton. I could have done very, very bad things to Joe Biden. I could have done very bad things to Barack Hussein Obama. I thought it was inappropriate to do so because you have to treat the office of the presidency with respect. Then I found out that they impeached me twice. And I certainly, even to this moment, I have — I can do whatever I want. They've done some very bad things. You just mentioned it. It was just mentioned in the form of a question. What they did — very illegal what they did. Many illegal things. But I view the presidency as a very sacred position. Very sacred position. Very important. Very sacred. A position where it has to be treated properly. They talk about the word impeachment. It was a very seldom-used word. With all of the years, it's happened very seldom. And they went after me twice. I won overwhelmingly. It was thrown out. Both of them were thrown out overwhelmingly. I was never even worried about it. But — and you — oftentimes, you have that one lunatic who starts screaming, Impeach him, impeach him. He — I think he lost his — he lost for congressman. Green. Congressman Green. He's a lunatic. He's a low-IQ person. But you can't treat the presidency with disrespect. And again, I've had my shot, and still do, at Biden, at Hillary Clinton, and Barack Hussein Obama. And I've had plenty of people say, Let's go get them. And I said, No, you can't do that to the presidency.
