The chairman of a Chicago bank 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. Just after the election, Mr. Calk, 54, had sent Mr. Manafort a list of 10 positions he wanted, including Treasury secretary, commerce secretary and defense secretary, according to the indictment unsealed in Federal District Court.

At the time, Mr. Manafort was trying to stave off foreclosure on several properties and desperately needed capital, the indictment said.

Kushner Replied ‘On It!’ After Manafort Sought Post for Banker

Shortly after Donald Trump’s 2016 election, his onetime campaign chief Paul Manafort wrote to Jared Kushner to ask the incoming administration to consider giving a “major appointment’’ to Manafort’s banker.

“On it!” Kushner replied to Manafort on Nov. 30, 2016.

That email exchange, which was admitted as evidence during Manafort’s tax-fraud trial last year, gained new significance Thursday with the unsealing of a federal indictment in New York. The new filing accused the banker, Stephen Calk, of extending loans to Manafort as part of an effort to bribe his way into a plum administration job.
