Now, Kushner’s association with Deutsche Bank is among a number of financial matters that could come under focus as his business activities are reviewed by special counsel Robert S. Mueller III, who is examining Kushner as part of a broader investigation into possible Russian influence in the election.

The October deal illustrates the extent to which Kushner was balancing roles as a top adviser to Trump and a real estate company executive. After the election, Kushner juggled duties for the Trump transition team and his corporation as he prepared to move to the White House. The Washington Post has reported that investigators are probing Kushner’s separate December meetings with the Russian ambassador to the United States, Sergey Kislyak, and with Russian banker Sergey Gorkov, the head of Vnesheconombank, a state development bank.

The Deutsche Bank loan capped what Kushner Cos. viewed as a triumph: It had purchased four mostly empty retail floors of the former New York Times building in 2015, recruited tenants to fill the space and got the Deutsche Bank loan in a refinancing deal that gave Kushner’s company $74 million more than it paid for the property.

Does this tie into the Russia investigation?
It might. When he talks to Congress about the investigation, Kushner is expected to be asked about whether his meeting with shady Russian banker Sergey Gorkov had anything to do with the search for buyers for the property, according to NBC News.

Trump biographer Timothy L. O'Brien has also speculated that Kushner might have been looking for help from the Russians to keep the building afloat. "The prospect that he may have been jockeying for Chinese or Russian financiers to bail out him and his family from a potentially disastrous investment at 666 Fifth Avenue presents complex but obvious conflicts of interest as well as the prospect of injudicious or self-serving White House policymaking," he wrote in Bloomberg View last month.
