On Monday, federal prosecutors working for Special Counsel Robert Mueller accused Paul Manafort, President Trump's former campaign chairman, of attempting to tamper with witnesses, and asked a judge to revoke his pre-trial release.
Manafort has been charged with, among other things, conspiracy against the United States and conspiracy to launder money. In court documents, an FBI agent wrote that at least one witness has said Manafort reached out and seemed to be trying to coach them on what to say about his lobbying practices, The New York Times reports. Per the documents, Manafort attempted to contact witnesses via telephone and an encrypted messaging program.
