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 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.

Manafort has been a subject of a longstanding FBI investigation into his dealings in Ukraine and work for the country's former president, Viktor Yanukovych. That investigation has been incorporated into the probe led by special counsel Robert Mueller, who is also scrutinizing Manafort's role in the Trump campaign as he looks into Russia's meddling in the 2016 election and any possible collusion with Trump associates.

Manafort, who led the Trump campaign for several months, has denied any wrongdoing. He also spoke behind closed doors to Senate investigators for an interview just one day before the search of his home.

The use of a search warrant indicates law enforcement officials have convinced a judge there is probable cause to believe a crime may have been committed. A house raid can be seen as an aggressive tactic given Manafort has been cooperating with congressional investigators and has turned over hundreds of pages of documents. It could indicate law enforcement was looking for records beyond what Manafort provided.

Word of the raid is the latest revelation about Mueller's investigation, which had been operating in relative secrecy compared with numerous congressional probes looking at the election. In recent days, it's become clear the former FBI director is using a grand jury in Washington in addition to one in the Eastern District of Virginia, where investigators also have been looking into former Trump national security adviser Michael Flynn.

Also, FBI agents have been asking witnesses since the spring about $530,000 worth of lobbying and investigative work carried out by Flynn's firm, Flynn Intel Group, according to a person familiar with the investigation. That work sought the extradition of an exiled Turkish cleric living in the U.S. Through his attorney, Flynn has declined to comment on the investigation.
