Story highlights Jeffrey Yohai provided information and documents to federal investigators

The information has been turned over to special counsel Robert Mueller

Washington (CNN) Former Trump campaign chairman Paul Manafort's son-in-law, Jeffrey Yohai, met with Department of Justice investigators in recent months, according to two sources familiar with the matter.

Yohai provided information and documents to federal investigators in New York more than two months ago, according to one of the sources.

The sources say the Justice Department was seeking cooperation related to the federal investigation into Manafort for possible money laundering or tax violations in his business dealings with pro-Russia parties in Ukraine.

The information has been turned over to special counsel Robert Mueller as part of his probe. It's unclear if any of the information Yohai provided has been useful for the investigation of Manafort.

Manafort spokesman Jason Maloni declined to comment on this story and an earlier Politico report Thursday that first discussed Yohai being approached about cooperation.
