Manhattan District Attorney Cyrus Vance’s charges against Chief Financial Officer Allen Weisselberg puts pressure on the longtime Trump executive to turn on his former boss and possibly provide evidence allowing prosecutors to bring a more expansive case. Vance and New York Attorney General Letitia James have been probing Trump’s business dealings for acts of fraud beyond the tax-related charges set to be unveiled Thursday. Charges by Vance could land Trump in jail while a successful case by James could cripple his company.
