In December, 2014, the sources said, Veselnitskaya, who then was involved in litigation pitting her Russian client against British-American financier William Browder, received a legal research memo reporting that the Ziff Brothers, two New York financiers allied with Browder, had made a large contribution to a Clinton charity.
The memo had been prepared by Fusion, which had been hired to conduct legal research on Browder by Baker and Hostetler law firm. The firm represented Russian businessman Denis Katsyv, who was engaged in disputes with Browder and U.S. prosecutors.
Veselnitskaya reportedly met with Simpson to discuss this memo she had ahead of her meeting with the Trump campaign. However, a source with knowledge of the testimony he gave to the Senate Judiciary Committee claimed he said he had no knowledge of that Trump Tower meeting until it was made public by the press.
Fusion GPS was initially funded by Republican donors to find opposition research on Trump, but dropped the project as he was clinching the nomination. The DNC and the Clinton campaign then continued to fund the research and that led to Christopher Steele‘s involvement and ultimately resulted in the notorious dossier.
