The Podesta Group, a prominent Washington-based lobbying firm with ties to the Democratic Party, is set for closing after it was implicated in the sprawling probe by special counsel Robert Mueller.

CNN reported Saturday that the Podesta Group's chief executive, Kimberley Fritts, told staff at a meeting Thursday that they should clear out their desk and that paychecks would discontinue after Nov. 15.

The firm was founded and run by Tony Podesta, the brother of John Podesta, the chairman of Hillary Clinton's 2016 campaign.

Mueller's investigation, looking into Russia's election meddling and whether the Kremlin colluded with President Trump's campaign, ensnared the Podesta Group in its indictments against former Trump campaign chairman Paul Manafort, regarding tax issues and non-disclosures in representing foreign interests.

Manafort has pleaded not guilty.
