The feds are turning up the heat on President Trump’s ex-campaign manager Paul Manafort by exploring whether he got $16 million in home mortgage loans after promising a Chicago banker a White House job, a new report said Wednesday.

Manafort took out three loans in December 2016 and January 2017 from Federal Savings Bank in Chicago for homes in Brooklyn and Bridgehampton, NBC News reported, citing sources.

Federal president Stephen Calk was named to then-candidate Trump’s council of economic advisers in August 2016, and special counsel Robert Mueller’s team is now scrutinizing the transactions to determine whether there was a secret deal between Manafort and Calk, the network reported.

Manafort left Team Trump that same August after revelations about the millions he had pocketed working for a shady pro-Russia political party in Ukraine — and Calk never got a White House gig.

Sources told NBC that the loans raised red flags at the bank and were questioned by top officials, and that one employee who felt pressured was cooperating with the feds.

Manafort formed a limited liability corporation called Summerbreeze, which took out a $9.5 million loan in December using his Hamptons property as part of the collateral.

In January 2017, Federal Savings Bank made Manafort and his wife mortgage loans of $5.3 million and $1.2 million for another property at 377 Union St. in Carroll Gardens, Brooklyn.

Also Wednesday, Reuters reported that Mueller filed new sealed criminal charges against Manafort and his former aide Rick Gates.

The single page, filed in federal court in Washington, DC, does not shed light on the nature of the new charges.

But last Friday, Mueller’s office revealed in a court filing that it had uncovered “additional criminal conduct” by Manafort in connection with a series of “bank frauds and bank fraud conspiracies” related to a mortgage on another property he owns in Fairfax, Virginia.

The White House and reps for Manafort and the bank did not respond to questions about the loans posed by the network.
