Roger Stone, through a formal court document his lawyers submitted, has apologized for an image posted to his Instagram account earlier in the day showing the face of the judge in his criminal case next to an apparent crosshairs symbol.

"Please inform the court that the photograph and comment today was improper and should not have been posted," Stone said in the court document. "I had no intention of disrespecting the court and humbly apologize to the court for the transgression."

Stone told CBS News the image had been misinterpreted and was not meant as a threat.

"I have objected to the manner in which my case was assigned to a specific judge rather than the judge being selected randomly," Stone told CBS News in a text message.

I do not believe that I have violated any order of the court and that these sentiments for within my First Amendment rights. Any inference that this in someway threatens the judge is false. Because it is open to misinterpretation I'm going to take it down."
