The FBI has conducted a pre-dawn raid on the home of Donald Trump’s former presidential campaign chairman, according to US media.
Paul Manafort, who led the then Republican candidate’s bid for the White House from June to August 2016, reportedly had tax documents and foreign banking records taken away.
The raid was ordered in connection with a probe into possible collusion between the Trump campaign team and Russia.
It took place on 28 July at Mr Manafort’s Virginia residence, a day after he was questioned by the Senate Intelligence Committee, the Washington Post said.
A spokesman for the political consultant confirmed the raid and said he had “consistently cooperated with law enforcement”.
Mr Manafort was the campaign manager when he attended a meeting with a Russian lawyer on the promise of damaging information about rival presidential-hopeful Hillary Clinton.
He resigned two months later amid reports he was under investigation over millions of dollars allegedly paid to him by the pro-Russia former Ukrainian President, Victor Yanukovych.
Meanwhile, the US President’s son, Donald Trump Jr, has turned over 250 pages of records to the Senate Judiciary Committee.
The Trump campaign itself sent 20,000 pages two days earlier as part of evidence into Russian interference with last year’s election.
Mr Trump Jr was present with Mr Manafort at the controversial meeting with Russian lawyer Natalia Veselnitskaya, which offered “very high-level and sensitive information… very useful to your father”.
Donald Trump praised his son’s “transparency” in releasing e-mails exchanged before the meeting.
The White House has previously branded any talk of perjury and treason over alleged links to Moscow as “ridiculous”.
It added the President was “frustrated” Russia continues to be an issue.
