Donald Trump doesn't do this often, but it's time to come clean.

He got there with a little help from "Sunday Morning Futures" host Mario Bartiromo.

She asked our former president, "Is there is anything you could look back on in 16 that you think maybe you want to do differently?"

Trump is famous for refusing to admit his mistakes. To this day, he's still convinced that he won the 2020 election. He's also said that there's nothing he has ever asked God for forgiveness for, because he's never done anything wrong.

That's why it was so surprising when Trump actually listed some things he should have done differently:

"The mistake would be people. I mean, I wouldn’t have put a guy like Bill Barr, and he was weak and pathetic. I wouldn’t have put Jeff Sessions. And there are some people that I wouldn’t have put in. You know, most people were good, but I had some people, we had Esper. I didn’t like him. He was incompetent. I thought we had other people I didn’t like."

Bartiromo then asked, "Why did you put them in the job then?"

"You put somebody in, and you think they are good," Trump replied.

"All of a sudden, I’m the president of the United States, and it’s like a different society. I was New York, and, you know, it was a different thing. So I didn’t know people. I became president. I’m riding down Pennsylvania Avenue with our first lady. I had 250 motorcycles. I had armies. I had everything. I said, do you believe it? We’re president. Take a look. This is wild, right? But I never was involved in that."

Bartiromo clarified, "So you didn’t know what to expect?"

Trump responded, "Well, I didn’t know the people. I know the people now better than anybody has ever known. The people I know, the good ones, the bad ones, the dumb ones, the smart ones."

Bartiromo then declared that "You didn’t drain the swamp like you said you would."

"I did drain the swamp," Trump shot back. "I fired Comey. I fired a lot of people. A lot of the people I had, I fired. I fired Comey very early. And, you know, there was a question as to whether or not you could. But I fired Comey. If I didn’t fire Comey, I don’t think I would have been able to serve out my term because that was a plot."
