Natalia Veselnitskaya made headlines as the Kremlin-connected Russian lawyer who met with then-candidate Donald Trump’s son, Donald Trump Jr., his campaign manager at the time, Paul Manafort, and Jared Kushner, the president’s son-in-law, at Trump Tower on June 9.

Veselnitskaya’s fingerprints seem to be all over the growing Trump-Russia scandal — so here’s what you need to know about her.

Natalia Veselnitskaya, 42, is a Russian lawyer whose ties to the Russian government began when she transitioned from working for a regional prosecutor’s office to private practice, representing Denis and Pyotr Katsyv, the shareholders of a variety of state-owned businesses, among others.

After graduating from Moscow State Law Academy in 1998, Veselnitskaya worked for three years in a regional prosecutor’s office outside Moscow, according to a court filing obtained by Heavy. She would later begin her own firm, Kamerton Consulting, in 2003, through which she started representing “large state-owned and private corporations, as well as clients from the real estate and banking sectors.” One such client was the Katsyv family, whose business dealings are headed by Denis and his father, Pyotr. Denis runs Prevezon Holdings, a real estate investment firm, and Pyotr is the vice president of Russian Railways, the state-run rail monopoly.

Veselnitskaya’s connection to the Russian government deepened when she became one of the leading challenging forces to the United States’ Magnitsky Act.

Passed by the U.S. Congress and signed by President Obama in December 2012, the Magnitsky Act placed sanctions on Russian officials connected to the death of Russian lawyer and auditor Sergei Magnitsky in a Moscow prison in 2009. While the Russian government charged Magnitsky with tax evasion after he was allegedly denied medical treatment and beaten to death by eight prison guards, the underlying motivation for Magnitsky’s death was reported to have been his work uncovering a $230 million tax fraud scandal involving Prevezon Holdings, Denis Katsyv’s company that Veselnitskaya had represented.

The sanctions so incensed Russian president Vladimir Putin that he responded by suspending all U.S. adoptions of Russian children. In addition, Putin sought to curtail sanctions related to the Magnitsky Act by fighting them in courts both in the U.S and in Russia. Veselnitskaya emerged as one of the major lawyers who took on this work, helping to establish the Delaware-based NGO, Human Rights Accountability Global Initiative Foundation (HRAGIF), an organization that, according to its bare-bones website, is ostensibly “dedicated to overturning the Russian adoption ban.”

However, a Bloomberg report shows that Hermitage Capital — the financial company for whom Magnitsky had been working when he discovered the $230 million tax fraud — sent a letter to the Department of Justice detailing how HRAGIF was actually a lobbying organization.

Veselnitskaya met with Trump Jr. in June 2016 under the pretense of supporting the Russian government’s broader plan to undermine Hillary Clinton’s campaign.

Russian publicist Rob Goldstone reached out to Donald Trump Jr. via email regarding documents that “would incriminate Hillary and her dealings with Russia and would be very useful to your father,” and it was Veselnitskaya who was slated to represent the Russian government in providing Trump Jr. with the information.

The June 9 meeting, which then-Trump campaign manager Paul Manafort and Trump's son-in-law Jared Kushner also attended, took place just two weeks after Trump secured the Republican nomination for president. According to a New York Times report, the proposed subject for the meeting was not the Magnitsky Act, as Donald Jr. originally claimed, but rather an exchange of damaging information on the Democratic presidential nominee, Hillary Clinton.
