The FBI and Justice Department have launched an investigation into whether the Podesta Group, the lobbying and public relations firm co-founded by Hillary Clinton presidential campaign chairman John Podesta, has any connections to alleged corruption that occurred in the administration of former President of Ukraine Viktor Yanukovych.

The federal probe is, CNN reports, "examining the work of other firms linked to the former Ukrainian government, including that of the Podesta Group."

The Podesta Group, run by John Podesta's brother Tony Podesta, was retained by the Russia-controlled firm UraniumOne in 2012, 2014, and 2015, to lobby Hillary Clinton's State Department. The lobbying firm was paid a total of $180,000 according to public records.

Yanukovych took office in February 2010. He was forced to flee to Russian after a political uprising in Ukraine. Federal prosecutors are probing the work Yanukovych's regime paid the Podesta Group to do while he was the head of the Ukrainian government.
