Kushner, who is married to first daughter Ivanka Trump, was acting as both an adviser to the Trump campaign and working at his real estate company when his firm received the loan from Deutsche Bank.

The White House told the Post that Kushner "will recuse from any particular matter involving specific parties in which Deutsche Bank is a party." Kushner and Deutsche Bank declined to comment to The Post on Sunday.

Kushner also reportedly made a personal guarantee on the loan, which he did not reveal on his financial disclosure form with the Office of Government Ethics.

A lawyer representing Kushner told the Post in a statement that Kushner was not required to disclose the loan because of guidance from the ethics office that "clearly states that filers do not have to disclose as a liability a loan on which they have made a guarantee unless they have a present obligation to repay the loan."
