This is not "just some lawyer from Russia." 
Veselnitskaya, the Kremlin lawyer who met with Kushner has also represented a Kremlin-backed, Cyprus-based Russian holding company, Prevezon, which reached a settlement in a case involving laundering $230 million from Russia that passed through Cyprus before being invested in New York real estate. U.S. Attorney Preet Bharara originally led the case against Prevezon, before he was forced to resign by Trump. Trump's Treasury Secretary, Wilbur Ross, was Vice-Chair of Bank of Cyprus as well as being one of its largest investors; the other Vice-Chair was a former KGB official and Putin ally. The largest investor in the corrupt Bank of Cyprus was Dmitry Rybolovlev, the Russian who bought a Florida mansion from Trump for $50 million more than Trump paid for it four years earlier. The Treasury Dept's FinCEN arm fined Trump's Taj Mahal $10 million for money laundering. Trump owes Deutsche Bank $300M; Deutsche Bank laundered billions through Cyprus.
