Stephen Calk, the CEO of Federal Savings Bank of Chicago and a economic adviser to Donald Trump during his 2016 presidential campaign, was charged with institutional bribery by federal authorities in Manhattan on Thursday, for allegedly extending $16 million in loans to former Trump campaign chairman Paul Manafort.

In exchange for the loans, Calk allegedly asked Manafort for assistance securing a high-ranking position, such as secretary of the Army, in the new administration.
