Former President Donald Trump could be facing a criminal indictment "relatively soon," according to his ex-attorney Michael Cohen.

Cohen predicted during an MSNBC interview on Wednesday that the Department of Justice (DOJ) would soon indict Trump over the recovery of classified documents from Mar-a-Lago, while the former president could also be forced to testify before Congress.

Cohen, who served as Trump's personal lawyer for more than a decade, suggested that the FBI's discovery of empty folders marked "top secret" during the August 8 raid of Trump's Florida home would be a central question to answer during any proceedings against the former president.

"If the adage that no one is above the law holds true, then Donald should have been indicted already and facing consequences," said Cohen. "I think that there's going to be an indictment and relatively soon. I believe there will also be congressional hearings with Donald in the hot seat where, you know, either he'll come in willingly—which I don't think he will—or via subpoena."

"The real questions that they have to be asking right now is, you know, where are the documents that were in the empty top secret files that were found at Mar-a-Lago?" he continued. "I mean, that's really the big question. And who did Donald give them to or show them to? ... Donald is a clear and present danger to the national security and safety of this country and if this doesn't prove it, I'm not sure that anything will."

Cohen has become one of Trump's fiercest critics in the years following his own criminal indictment. He was sentenced to three years of home confinement in 2018 after pleading guilty to federal tax crimes, lying to Congress and violations of campaign finance laws.

Cohen suggested on Wednesday that his former client kept documents containing nuclear secrets at Mar-a-Lago so they could be used for "extortion" purposes in the event that he was indicted.

Materials detailing the nuclear-defense readiness capabilities of a foreign government were among the items recovered during the FBI raid, according to a Tuesday report from The Washington Post.

"This is all about power for Donald Trump," Cohen said. "This is all about him still remaining relevant and exerting the power. Whether it's going to be over the United States as extortion, that in the event you indict me or even members of my family... If you indict me or try to incarcerate me, I have nuclear secrets that I have instructed some of my followers to turn over to our adversaries."

"That's what I believe," he continued. "It's all about him maintaining power. But not just over this country, over foreign countries as well... That's why we have the Presidential Records Act. That's why we have laws... We're supposed to know that these documents are in the possession of individuals who are supposed to have them in secured locations, not somewhere in his office at Mar-a-Lago."
