Keeping up with every twist and turn of special counsel Robert Mueller's FBI probe into the Trump campaign is practically a full-time job. But knowing who is cooperating with the Mueller investigation is key to understanding what's at stake — and what could eventually come of the whole ordeal. Not to mention, the list of people with ties to President Trump who are helping Mueller isn't exactly a short one.
It could also continue to grow. Donald Trump's longtime personal lawyer, Michael Cohen, has become a key figure in the president's legal drama. That's thanks in part to the $130,000 payment he made to an adult film star who claims she had an affair with Trump in 2006. Cohen has been under a separate criminal investigation himself in the Southern District of New York, and multiple media outlets reported this week that he may start cooperating with federal prosecutors there. If he cuts a plea deal in New York, he'll "likely be obligated to provide Mueller’s team relevant information too," Vox reports.
But even without Cohen, Mueller's team already has a roster of former Trump campaign staffers and allies who signed on to cooperate. Most of them agreed to assist the probe because they faced legal problems of their own in connection to the investigation. At the end of the day, though, why each is cooperating doesn't change the fact that they're all talking.
