Surrounded by hecklers shouting "lock him up," former Trump adviser Roger Stone declared Friday after a court appearance in Fort Lauderdale, Florida, that he will fight "politically motivated" charges of obstruction, false statements and witness tampering brought by special counsel Robert Mueller in his investigation of alleged Trump campaign collusion with Russia.

Stone – who was arrested in a pre-dawn raid Friday morning at his home by FBI agents in tactical gear with their guns drawn – emphasized that the charges "related in no way to Russian collusion or collaboration" during the 2016 campaign.

"I am falsely accused of making false statements during my testimony to the House Intelligence Committee," he said, calling Mueller's probe a "two-year inquisition."

Stone, who was released on $250,000 bail, said he found it "disturbing" that the special counsel's office distributed a news release prior to informing his attorneys of the charges.

"At the crack of dawn, 29 FBI agents arrived at my home with 17 vehicles with their lights flashing when they simply could have contacted my attorneys, and I would have been more than willing to surrender voluntarily," said Stone, competing with the ongoing din of heckling.

"They terrorized my wife, my dogs while I was taken to the FBI facility," Stone said.

He said he will plead not guilty to the charges, which include allegations that he worked to obstruct the House Intelligence Committee's investigation into Russian interference by denying he had records sought by the committee and persuading a witness to provide false testimony.

"I will defeat them in court," Stone said of the seven counts. "I believe this is a politically motivated investigation."

He inferred that, facing prison time, Mueller's team, was pressuring him to become a witness against President Trump.

"There is no circumstance whatsoever under which I will bear false witness again the president, nor will I make up lies to ease the pressure on myself," he said.

"I look forward to being fully vindicated."

'The only thing worse ... '

Stone, who describes himself as a political showman and dirty-trickster, opened his remarks saying, "The only thing worse than being talked about is not being talked about."

As he made his way to the microphones he flashed the iconic "V" for victory sign of Richard Nixon. Stone, who has a Nixon tattoo on his back, began his political career working for Nixon.

Mueller's team is accusing Stone of communicating with unnamed Trump campaign officials about the WikiLeaks release of hacked emails of Democrats during the 2016 campaign.

Jay Sekulow, a lawyer for Trump, said Friday that the indictment "does not allege Russian collusion by Roger Stone or anyone else."
