From the NBC report:
Federal investigators are probing whether former Trump campaign chair Paul Manafort promised a Chicago banker a job in the Trump White House in return for $16 million in home loans, two people with direct knowledge of the matter told NBC News.
Manafort received three separate loans in December 2016 and January 2017 from Federal Savings Bank for homes in New York City and the Hamptons.
The banker, Stephen Calk, president of the Federal Savings Bank, was announced as a member of candidate Trump’s Council of Economic Advisers in August 2016.
Special counsel Robert Mueller’s team is now investigating whether there was a quid pro quo agreement between Manafort and Calk. Manafort left the Trump campaign in August 2016 after the millions he had earned working for a pro-Russian political party in Ukraine drew media scrutiny. Calk did not receive a job in President Donald Trump’s cabinet.
