President Donald Trump said in an exclusive interview on "Fox & Friends" that defendants "flipping" for a better deal should "almost be illegal."

Trump's former attorney, Michael Cohen, pleaded guilty to eight charges in federal court on Tuesday related to then-candidate Trump's presidential campaign.

Cohen admitted to violating federal campaign finance laws by arranging hush money payments to adult film star Stormy Daniels and former Playboy model Karen McDougal -- who allegedly had affairs with Trump and were paid to stay silent in the lead-up to the 2016 election -- "at the direction" of Trump.

Trump said for decades he's been seeing people charged with crimes "flip" and implicate someone higher up the chain.

"It almost ought to be outlawed. It’s not fair," Trump, noting that Cohen was able to lower his potential sentence from ten years or more to three to five years.

"I've seen it many times. I've had many friends involved in this stuff. It’s called flipping and it almost ought to be illegal," Trump said. "You get ten years in jail, but if you say bad things about somebody, in other words make up stories, they just make up lies. …They make up things and now they go from ten years to they’re a national hero. They have a statue erected in their honor."

"It’s not a fair thing. But that’s why he did it. He made a very good deal."

Cohen was once looked at as one of the Trump's most committed and loyal backers, even going so far as to say he would "take a bullet" for him.

Trump, however, disputed the claim that Cohen served as his "fixer," describing him as "not somebody that was with me that much."

Trump was also asked if he was considering pardoning his former campaign chair, Paul Manafort, who has been found guilty of eight charges of banking and tax fraud.

Trump said he has "great respect" for Manafort, as the majority of consultants and lobbyists working in Washington, D.C., operate in a similar way. But he declined to answer whether he'd pardon Manafort, who faces a second trial in Washington, D.C.
