Investigators have now progressed from a general focus on Jared Kushner's meetings with Russians last December to specifically scrutinizing his financial dealings. The Washington Post reports:
The Washington Post had earlier reported that investigators were scrutinizing separate meetings that Kushner held with Russians in December — first with Russian ambassador Sergey Kislyak and then with Sergey Gorkov, the head of a state-owned Russian development bank. At the time of that report it was not clear that the FBI was investigating Kushner’s business dealings. [...]
At the December meeting with Kislyak, Kushner suggested establishing a secure communications line between Trump officials and the Kremlin at a Russian diplomatic facility, according to U.S. officials who reviewed intelligence reports describing Kislyak’s account.
The White House has said the subsequent meeting with the banker was a pre-inauguration diplomatic encounter, unrelated to business matters. The Russian bank, Vnesheconombank, which has been the subject of U.S. sanctions following Russia’s annexation of Crimea, has said the session was held for business reasons because of Kushner’s role as head of his family’s real estate company. The meeting occurred as Kushner’s company had been seeking financing for its troubled $1.8 billion purchase of an office building on Fifth Avenue in New York, and it could raise questions about whether Kushner’s personal financial interests were colliding with his impending role as a public official.
The piece notes that this is an early stage of the investigation. But Kushner's December meetings, which came to light later than Flynn's, have become increasingly problematic over time. In particular, he's come up with no satisfying explanation for either of them, not to mention his initial failure to disclose them.
