Trump’s former campaign adviser Roger Stone pleaded not guilty in federal court in Washington, D.C., on Tuesday to charges in Special Counsel Robert Mueller’s investigation. In a surprise early-morning raid on his home, Stone was indicted Friday on charges including obstruction of justice and witness tampering, related to alleged lies he told to the House Intelligence Committee regarding WikiLeaks and the Trump campaign, and his alleged attempt to convince another witness to lie. In the hours after the raid, Stone claimed that he would be “completely vindicated.” During his plea Tuesday, Stone denied the charges of of obstruction, witness tampering, and making false statements.
