Trump Tower lawyer Natalia Veselnitskaya has been accused of an elaborate new plot to pervert the course of justice.

Veselnitskaya, the pro-Kremlin lawyer who attended the notorious 2016 Trump Tower meeting with Donald Trump Jr. and Jared Kushner, allegedly doctored official documents, according to leaked files viewed by The Daily Beast.

The lawyer, who was tasked with pushing one of President Vladimir Putin's most cherished propaganda campaigns in the U.S., has already been indicted on obstruction of justice charges by prosecutors for the Southern District of New York.

New documents allege that Veselnitskaya or her team may have employed a similar strategy to tamper with supposedly independent evidence submitted to a court in a related case in Switzerland, where Veselnitskaya's clients--Denis Katsyv and his company Prevezon--were at the center of a massive tax fraud and money-laundering investigation that was dropped last year.
