US Federal Bureau of Investigation conducted a predawn raid of former Donald Trump presidential campaign chairman Paul Manafort’s home in Alexandria, Virginia, a spokesperson for Manafort confirmed Wednesday.

FBI agents, using a wide-ranging search warrant, raided Manafort’s home without advance warning in the predawn hours of July 26, the day after he met voluntarily with the U.S. Senate Intelligence Committee members, the Washington Post reported, quoting people familiar with special counsel Robert Mueller who is investigating ties between Trump’s campaign and Russia.

Manafort’s spokesperson confirmed the report in a statement.

“FBI agents executed a search warrant at one of Mr. Manafort’s residences. Mr. Manafort has consistently cooperated with law enforcement and other serious inquiries and did so on this occasion as well,” he added.
