Credico's social media post came after the Justice Department on Tuesday backed off a prior sentencing proposal for Stone, a longtime informal political adviser to Trump. The president had been critical of prosecutors' initial recommendation, which called for Stone to serve a prison term of roughly seven to nine years.

Following that intervention by the Justice Department, the four attorneys who had shepherded Stone's prosecution either resigned or notified the court on Tuesday that they were stepping off the case. Trump suggested in a tweet on Wednesday that they were perhaps "Rogue prosecutors."

A federal jury found Stone guilty in November of impeding congressional and FBI investigations into connections between the Russian government and Trump's 2016 campaign. Stone had told lawmakers in 2017 that Credico acted as his backchannel to WikiLeaks founder Julian Assange during the election — an allegation Credico has denied.

Credico was interviewed by former special counsel Robert Mueller's team on several occasions in 2018. He went on to appear at Stone's trial, which revealed a series of hostile and vulgar text messages Stone sent to Credico in an alleged effort to intimidate him into repeating Stone's version of events in testimony before Congress.

Although Stone has claimed his comments were in jest, prosecutors pointed to the messages to justify the bulk of his suggested prison time. "Prepare to die, cocksucker," Stone wrote to Credico in one instance. He also told Credico, who has a therapy dog, that he would "take that dog away from you."

Credico recently wrote to the court saying he did not think Stone was threatening him physically, but prosecutors noted that during the trial, Credico said he was concerned that Stone's statements could encourage others to become violent.
