Former President Donald Trump says that he made a "mistake" with regard to some of the people whom he selected to be part of his administration's cabinet. 

Trump made the admission during an interview that he recently did on the Fox News Channel's Sunday Morning Futures with host Maria Bartiromo.

There, Bartiromo asked Trump, "Is there anything you could look back on in '16 that you think maybe you want to do differently this time around?"

Bartiromo, of course, asked Trump this question in light of the fact that he is currently running for the U.S. presidency. He, in fact, is the clear favorite to win the Republican Party's 2024 presidential nomination.

Trump answered Bartiromo's question in the affirmative.

"The mistake would be people," Trump said. "I mean, I wouldn't have put a guy like [former U.S. Attorney General] Bill Barr. He was weak and pathetic. I wouldn't have put [U.S. Attorney General] Jeff Sessions, and there are some people that I wouldn't have put in."

The former president continued, "You know, most people were good, but I had some people - we had [Dr. Mark] Esper. I didn't like him. He was incompetent. I thought we had other people I didn't like."

Trump's response prompted Bartiromo to ask him, "Why did you put them in the job, then?"

"Because every president puts somebody in and you think they're good [at first]," Trump replied.

The former then proceeded to explain how, when he became president, he was an outsider. Trump said that, accordingly, he did not really know many of the people who ended up becoming part of his administration.

In 2024, however, Trump said that things will be different because he knows "the people now better than anybody has ever known [them]."

"The people I know - the good ones, the bad ones, the dumb ones, the smart ones," Trump said.

Trump, during the interview, did not really go into whom he may select as his cabinet members were he be elected to a second term in 2024. But, the former president did suggest that some of his 2024 Republican rivals - including U.S. Sen. Tim Scott (R-SC) - could end up in his administration.

About Scott, Trump told Bartiromo:

I think he's a very good guy. And, we did opportunity zones together. It's never been talked about. It's one of the most successful economic development things ever done in this country. And, Tim is very good. I mean, I could see Tim doing something with the administration, but he's in right now campaigning…. But Tim is a talented guy, and you have other very talented people.
