In late July, FBI agents raided Trump campaign chairman Paul Manafort's home under a search warrant. Manafort has been a person of interest in the congressional and federal investigations into whether members of President Donald Trump's campaign colluded with Russian officials to influence the 2016 presidential race.
On Aug. 9, sources familiar with special counsel Robert Mueller's probe into Russia disclosed that FBI agents working with the investigation had already raided and collected evidence from Manafort's residence. The former chairman had already been cooperating with the congressional investigations into the Trump campaign, The Washington Post reports.
On July 26, FBI agents conducted a predawn raid on Manafort's home in Alexandria, Virginia. They had reportedly been granted a broad search warrant by a federal judge and had given Manafort no prior notice. The agents collected numerous documents from the residence. The contents and significance of the gathered materials have not been disclosed.
Manafort spokesman Jason Maloni confirmed that the raid took place and asserted that the former campaign chairman was fully cooperating with the investigation.
"FBI agents executed a search warrant at one of Mr. Manafort's residences," Maloni told NPR. "Mr. Manafort has consistently cooperated with law enforcement and other serious inquiries and did so on this occasion as well."
Manafort had already turned over several of his records to the House Intelligence Committee, the Senate Intelligence Committee, and the Senate Judiciary Committee. An adviser close to the Trump administration asserted that if FBI agents "wanted the documents, they could just ask [Manafort] and he would have turned them over."
On Aug. 3, officials disclosed that Mueller had impaneled a grand jury for the Russia probe in Washington, D.C. There had already been a grand jury for the investigation into former White House National Security Adviser Michael Flynn, according to The Hill.
In April 2016, Manafort was appointed chairman of the Trump campaign. In August 2016, Manafort resigned from his position following reports that he had allegedly received $12.7 million from the Ukrainian Party of Regions, an administration that was accused of serving as a puppet state for Russian President Vladimir Putin, according to Politico.
On June 28, Manafort officially registered as a foreign agent and disclosed that his consulting firm had been paid $17 million by the Party of Regions, The Guardian reports.
In June 2016, Manafort attended the meeting between Donald Trump Jr. and Russian attorney Natalia Veselnitskaya in Manhattan, New York. Trump Jr. would later disclose that he took the meeting on the promise that Veselnitskaya could provide damaging information about former Secretary of State Hillary Clinton.
On Aug. 2, both Manafort and Trump Jr. turned over roughly 650 documents to the Senate Judiciary Committee's Russia probe, Bloomberg reports.
