Trump friend Roger Stone pleads not guilty

WASHINGTON (AP) — Donald Trump’s longtime friend Roger Stone has pleaded not guilty to charges in the special counsel’s Russia investigation.

Stone appeared Tuesday for his arraignment at the federal courthouse in Washington after spending the weekend blasting special counsel Robert Mueller’s case against him as politically motivated.

The self-proclaimed dirty trickster was arrested last week during a pre-dawn raid at his Florida home. He is charged in a seven-count indictment with obstruction, lying to Congress and witness tampering. Prosecutors say he lied about the contents of his discussions with the Trump campaign involving WikiLeaks and hacked material damaging to Hillary Clinton that the anti-secrecy group released during the 2016 campaign.

Stone is also accused of corruptly influencing the testimony of another witness.
