Five potential witnesses against former Trump campaign chairman Paul Manafort, including accountants and bankers, were identified Monday as the federal judge in the case granted the defense more time to review tens of thousands of documents handed over in recent weeks.

Among the possible witnesses granted immunity in the case are people from Kositzka, Wicks and Company, an accounting firm used by Manafort, and others who appear to have worked for the Federal Savings Bank in Chicago, which provided him with millions of dollars in mortgage loans.

U.S. District Judge T.S. Ellis III pushed back Manafort's bank- and tax-fraud case after defense lawyers complained that they didn't have adequate time to review 120,000 pages of documents they received this month from prosecutors working with special counsel Robert Mueller.
