Roger Stone speaks at the American Priority Conference in Washington. Stone, an associate of President Donald Trump, has been arrested in Florida.

Roger Stone, a confidant of President Donald Trump, was arrested in the special counsel's Russia investigation in a pre-dawn raid at his Florida home on Friday and was charged with lying to Congress and obstructing the probe.

The seven-count indictment against Stone, a self-proclaimed "dirty trickster," is the first criminal case in months from special counsel Robert Mueller. It provides the most detail to date about how Trump campaign associates were aware in the summer of 2016 that emails had been stolen from the Hillary Clinton campaign and wanted them released. It alleges that unnamed senior Trump campaign officials contacted Stone to ask when the stolen emails might be disclosed.

The indictment does not charge Stone with conspiring with WikiLeaks, the anti-secrecy website that published the emails, or with the Russian officers Mueller says hacked them. Instead, it accuses him of witness tampering, obstruction and false statements about his interactions related to WikiLeaks' release. Some of those false statements were made to the House intelligence committee, according to the indictment.

CNN recorded video of the raid at Stone's Fort Lauderdale home, showing FBI agents in combat gear using large weapons and night-vision equipment, running up to the home and banging repeatedly on the door. "FBI open the door!" one shouts. "FBI, warrant!" Stone could then be seen in the doorway in his sleepwear before he was led away, CNN reported.

Stone is the sixth Trump aide charged in Mueller's investigation into potential co-ordination between Russia and the Trump campaign and the 34th person overall. The investigation has laid bare multiple contacts between Trump associates and Russia during the campaign and transition period and efforts by several to conceal those communications. The case against Stone comes weeks after Trump's former national security adviser was castigated by a judge in open court and just hours before his ex-campaign chairman was due in court on allegations that he had lied to Mueller's prosecutors.
