Michael Cohen, former personal lawyer for U.S. President Donald Trump, is expected to part ways with attorneys handling the criminal investigation into his business dealings, a person familiar with the matter told Reuters.

Cohen's lawyers Stephen Ryan and Todd Harrison of McDermott, Will & Emery LLP, a Washington and New York firm, are expected to complete a review of documents seized by federal prosecutors in an April raid on Cohen's home and office. The court has set a Friday deadline for completion of the review.

Cohen will hire other counsel once the review is complete, the person familiar with the matter told Reuters on condition of anonymity. Cohen wants to hire a lawyer who has a relationship with the U.S. prosecutor's office in Manhattan, the source added.
