Manafort proposed in a confidential strategy plan as early as June 2005 that he would influence politics, business dealings and news coverage inside the United States, Europe and the former Soviet republics to benefit the Putin government, even as U.S.-Russia relations under Republican President George W. Bush grew worse.

"We are now of the belief that this model can greatly benefit the Putin Government if employed at the correct levels with the appropriate commitment to success," Manafort wrote in the 2005 memo to Deripaska. The effort, Manafort wrote, "will be offering a great service that can re-focus, both internally and externally, the policies of the Putin government."

Manafort told Deripaska in 2005 that he was pushing policies as part of his work in Ukraine "at the highest levels of the U.S. government — the White House, Capitol Hill and the State Department," according to the documents.
