Michael Cohen says he 'would not be surprised' if FBI informant was one of Trump's kids or Jared Kushner

• Michael Cohen suspects the possible informant involved in the FBI's Mar-a-Lago raid is in Trump's "inner circle."
• "I would not be surprised to find out it is Jared [Kushner] or one of his children," Cohen told Insider.

Donald Trump's ex-personal attorney and fixer Michael Cohen suspects that the possible informant involved in the FBI's raid on the former president's Mar-a-Lago estate in Florida is one of his own kids or his son-in-law, Jared Kushner.

"It's definitely a member of [Trump's] inner circle," Cohen told Insider on Thursday, adding, "I would not be surprised to find out it is Jared or one of his children."

"Who else would know about the existence of a safe and the specific contents kept inside?" Cohen said.

A representative for Trump did not immediately respond to Insider's request for comment on Thursday.

The FBI on Monday executed a search warrant at Trump's home in Palm Beach, Florida, and even broke into a safe there, Trump announced at the time as he accused the feds of "prosecutorial misconduct."

Trump and his allies also suggested the baseless conspiracy theory that the FBI planted evidence during the raid.

"Everyone was asked to leave the premises, they wanted to be left alone, without any witnesses to see what they were doing, taking or, hopefully not, 'planting,'" Trump wrote on his social-media app, Truth Social.

However, Trump's own lawyer cast doubt on those claims.

Sources told ABC News that the FBI raid was related to 15 boxes of documents that Trump had moved from the White House to Mar-a-Lago upon leaving office.

Earlier this year, the National Archives asked the Justice Department to investigate whether Trump broke the law when he took the boxes, some of which contained classified information.

Additionally, sources told both Newsweek and The Wall Street Journal that an informant tipped off authorities that classified government documents may have been improperly stored at Mar-a-Lago.

And people in Trump's orbit have started finger-pointing amid growing paranoia about an informant, Rolling Stone reported.

Fox News White House correspondent Jacqui Heinrich said in a tweet on Thursday that a federal law enforcement source told her that probable cause for the FBI search warrant at Mar-a-Lago "very likely" came from a member of the Secret Service.

"Nothing good comes after the FBI raids your property — except my elation that it involved Trump," Cohen, who served as Trump's personal lawyer and confidant for almost a decade, told Insider.

In 2018, federal authorities raided Cohen's home and office as part of a criminal investigation into Trump's illegal hush-money payment to the adult-film actress Stormy Daniels.

That year Cohen pleaded guilty to multiple felonies, including tax evasion, campaign finance violations, and bank fraud, and was sentenced to three years in prison.

Since pleading guilty, Cohen has become one of Trump's fiercest critics and is said to be cooperating in a number of criminal and civil investigations into his former boss.

"I predict an indictment and conviction on more than just possessing classified documents," Cohen told Insider of Trump. "The Democratic adage that no one is about the law will ring true."

The Department of Justice is investigating Trump as part of its criminal probe into the deadly January 6, 2021, Capitol siege.
