“A Chicago bank chairman has been indicted in Manhattan on a charge that he issued millions of dollars in high-risk loans to President Trump’s former campaign chairman, Paul Manafort, in an effort to obtain a senior position in the administration, federal authorities said on Thursday. Prosecutors said the chairman, Stephen M. Calk of Federal Savings Bank, pushed the bank to give Mr. Manafort $16 million in loans in 2016 in exchange for help in procuring an appointment for Mr. Calk.”
