WASHINGTON (AP) — FBI agents looking for financial documents have searched one of the homes of President Donald Trump’s former campaign chairman, Paul Manafort, whose past foreign political work has been swept into the investigations into Russian interference in the 2016 election. A Manafort spokesman confirmed the search Wednesday.

Manafort spokesman Jason Maloni said in a statement that FBI agents had obtained a warrant and searched one of Manafort’s homes, but he would not say when the search occurred or what it was for.

“Mr. Manafort has consistently cooperated with law enforcement and other serious inquiries and did so on this occasion as well,” Maloni said.
