Roger Stone

Trump has had a combustible relationship with Stone, the renegade GOP operative who was once partner at a Washington lobbying firm with Manafort.

Trump called Stone a “stone-cold loser” and described him as always trying to take credit for things he didn’t do in a 2008 profile in The New Yorker.

But Stone acted as an adviser to the Trump campaign early in 2015, before leaving under odd circumstances.

Stone later said he planned to launch a pro-Trump super-PAC. At the time, Lewandowski described that effort to The Hill as a “big league scam” designed to profit off Trump’s name.

But Trump and Stone appear to have patched things up and are said to speak regularly, even if Trump will never publicly acknowledge the relationship.

Stone is believed to have been instrumental in recruiting Manafort for the campaign, and is as colorful a political figure as they come. He worked for the Nixon campaign and has a tattoo of the former president on his back.
