Fusion GPS investigated Browder on behalf of the Russian government after Magnitsky alleged Russia stole money from Hermitage Capital.
"So they're trying to play both sides against the middle, and I hope the country wakes up to the threat Russian Federation presents to us all", Graham said.
Browder has been battling the Russian government for over a decade.
Browder got kicked out of Russian Federation after helping to expose an alleged $230 million fraud, where he claims companies his shareholders owned were essentially stolen and tax revenue taken.
Browder's testimony claims that Veselnitskaya hired Fusion GPS through lobbying firm Baker Hostetler to undermine the Magnitsky Act on behalf of Russian interests, and that the firm helped to organize a Washington D.C. -based premiere of a "fake documentary" about himself as well as his lawyer Sergei Magnitsky.
First was Kushner making a statement about his meeting with the Senate staff investigating Russian meddling in the 2016 election and collusion with the Trump campaign using the White House as a backdrop - standing in front of a podium emblazoned with the White House seal.
'What they were willing to offer in return I don't know.
Simpson also cut a deal with Judiciary Committee Chairman Chuck Grassley, R-Iowa, in which he'll speak with committee members or staffers privately in the way Trump's son-in-law, Jared Kushner, did this week with the Senate and House Intelligence Committees. "And so it's a real effect", Browder said.
Congress then passed sanctions legislation in response in order to punish officials believed to be involved in Magnitsky's death.
While it would be very challenging for Russian Federation to repeal the Magnitisky Act entirely, even with the buy-in of the USA president, there are loopholes to relieve pressure on some of the high-ranking billionaires in Putin's kleptocracy.
Adam Hickey, the deputy assistant attorney general at the Justice Department's National Security Division, defended the small number prosecutions, saying there is a high burden of proof for such cases because prosecutors have to show the agent is being willfully deceptive. And I would not understate the value of the Magnitsky Act in terms of the consequences, because not only does it freeze the assets that are held in America, but the moment that you get onto the Magnitsky list, you get put on the OFAC sanctions list (Office of Foreign Assets Control), which is a (U.S.) Treasury sanctions list. "You basically become a financial pariah".
The Russian lawyer expressed doubt about the United States' readiness to remember democratic principles and hear all arguments that will be presented in an "honest and open competitive and public process".
If all that weren't damning enough, Thor Halvorssen, president and CEO of the Human Rights Foundation, has also provided eye-opening testimony to the Judiciary Committee alleging that Fusion GPS is also operating in violation of the Foreign Agent Registration Act, owing to its involvement in an oddly similar scheme to prevent scrutiny of Venezuelan kleptocrats that are funneling money out of the oil-rich but unstable socialist country. In his recent book, "Red Notice: A True Story of High Finance, Murder and One Man's Fight for Justice", he recounts his life and expulsion from Russian Federation, as well as his campaign for justice for Magnitsky.
He described it as "a loophole you can drive a truck through in the Lobbying Disclosures Act".
The opposition research firm that produced the explosive dossier alleging ties between the Trump campaign and Russian Federation issued a statement Thursday denying that it needs to register as a foreign agent, or that it broke the law in not doing so a year ago.
Browder - a former hedge fund manager who spearheaded the passage of the Magnitsky Act after his tax lawyer, Sergei Magnitsky, died in a Russian prison in 2009 - alleged in a complaint filed with the Treasury Department past year that Fusion's work for the USA law firm BakerHostetler violated the Foreign Agents Registration Act because it served Russian government interests.
"If people who haven't registered as foreign agents are convicted, prosecuted, and imprisoned, then everyone in the future will register as foreign agents", Browder argued.
