Search warrant executed at home of former Trump campaign manager Paul Manafort

WASHINGTON, D.C. -- Federal authorities issued and executed a search warrant on a home in Virginia belonging to former Trump campaign chairman Paul Manafort in the last two weeks, ABC News has learned.

Sources tell ABC the search warrant, issued by the FBI, stems from the ongoing investigation by Special Prosecutor Robert Mueller into alleged collusion between the Trump campaign and the Russian government.

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. The Washington Post, which first reported the raid, said it occurred the morning of July 26 at Manafort's home in Alexandria, Va.

"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. Special Counsel Robert Mueller is also investigating Manafort as part of his probe into Russia's meddling in the 2016 election and any possible collusion with Trump associates.

Manafort has denied any wrongdoing. He has also cooperated with congressional committees investigating the election interference. Manafort recently spoke with staff of the Senate Intelligence committee about a June 2016 meeting he attended with Donald Trump Jr. That meeting was described to Trump Jr. in emails as part of a Russian government effort to help the Trump campaign.

Manafort has also turned over documents to the Senate Intelligence and Judiciary committees.

The Trump campaign sent over more than 20,000 pages of documents to the committee last week on August 2, the deadline to submit documents to the committee.

Law enforcement authorities seeking to obtain a search warrant must generally establish to a judge that there is probable cause to believe that a crime may have been committed. Applications for such warrants tend to be detailed about the evidence that agents are looking for and the nature of the criminal activity they are investigating.

Manafort led the Trump campaign for several months.

Just last month, Manafort registered as a foreign agent for past work on behalf of Ukraine, his spokesperson confirmed at the time to ABC News.

Within the last few weeks, ABC News has learned President Trump's presidential campaign, Manafort, and his son Donald Trump Jr. have started handing over documents to the Senate Judiciary Committee in compliance with the panel's investigation into possible Russian election interference.

Manafort produced about 400 pages, including his foreign agent advocacy paperwork around the same time. In letters to Manafort and Trump Jr., the Judiciary Committee leaders asked for all documents related to their June 2016 meeting with Russian lawyers, as well as any communications or records of attempts to obtain information from Russians about Hillary Clinton or the 2016 presidential campaign.
