Federal prosecutors say in a court filing that the criminal probe that led them to raid the offices of Donald Trump's personal lawyer this week is focused on his "personal business dealings."

In the filing with a court in New York, prosecutors blacked out a section describing what crime they believe Trump attorney Michael Cohen has committed. But they provided new details on the investigation, which they said has been going on for months.

They said agents had already searched multiple email accounts maintained by Cohen.

The filing said none of those emails was exchanged with Trump.

Earlier, Cohen tried to prevent the government from using materials the FBI seized in a search of his office and residence this week.

Federal agents raided Cohen's Manhattan office, home and hotel room Monday, seizing records on a variety of subjects, including payments that were made in 2016 to women who might have damaging information about Trump.

FBI and Justice Department officials in Washington and New York have refused to discuss the case publicly or say what crimes they are investigating, but people familiar with the investigation have told The Associated Press the search warrant used in the raids sought bank records, business records on Cohen's dealing in the taxi industry, Cohen's communications with the Trump campaign and information on payments made to a former Playboy model and a porn actress who say they had affairs with Trump.

Those people spoke on condition of anonymity to discuss the confidential details.

It was unclear how much prosecutors might have to reveal about the investigation in open court in Friday's hearing.

Cohen has denied wrongdoing. Cohen's lawyer, Stephen Ryan, declined to comment to The Associated Press.

Trump has called the raids a "witch hunt," ''an attack on our country," and a violation of rules that ordinarily make attorney client communications confidential.

Those confidentiality rules can be set aside under certain circumstances if investigators have evidence that a crime has been committed.

Public corruption prosecutors in the U.S. attorney's office in Manhattan are trying to determine, according to one person familiar with the investigation, if there was any fraud related to payments to Karen McDougal, a former Playmate, and Stephanie Clifford, who performs under the name Stormy Daniels.

McDougal was paid $150,000 in the summer of 2016 by the parent company of the National Enquirer under an agreement that gave it the exclusive rights to her story, which it never published. Cohen said he paid Daniels $130,000 in exchange for her silence about her claim to have had a one-night-stand with Trump.

The White House has consistently said Trump denies either affair.
