"The loan was secured while Kushner was both the head of the company and playing a leading role in running the presidential campaign of his father-in-law, Donald Trump," according to the newspaper.
The request does not appear related to special counsel Robert Mueller’s investigation into Russia’s role in the election, the Washington Post reported.
"We do not understand why anyone would look at this fairly routine transaction other than as a reaction to what appears to be politically motivated media coverage," Kushner real estate company spokeswoman Christine Taylor said as quoted by the Post. Nonetheless, we have cooperated with inquiries."
Deutsche Bank is one of the biggest lenders to both the Kushner companies and the Trump Organization, which had about $364 million in debt to the bank as of last year, according to the report.
Federal prosecutors in Brooklyn have been probing Deutsche Bank, issuing a news release in September about charges brought against the financial institution in an unrelated case, the report noted.
Kushner has yet to comment on the media report.
