Roger Stone, Donald Trump’s longtime political adviser, reportedly posted and then deleted an inflammatory online call that former CIA Director John Brennan be “hung” for treason.

Stone, 66, is under a gag order as he awaits federal trial on charges related to his work on Trump’s 2016 campaign. He was sternly reprimanded by U.S. District Judge Amy Berman Jackson in February for a social media post that featured the judge’s face with crosshairs.

Stone faces trial in November on charges that include lying to Congress, obstructing justice and witness tampering for activities linked to the Trump campaign.

The Brennan Instagram story was first reported on Twitter Sunday morning by CNN’s Brian Stelter. CNN security analyst Sam Vinograd soon wondered in a tweet why the Brennan photo with comment hadn’t been taken down 55 minutes after it was posted.

Several screen shots of the reported post on Twitter — and reported by Newsweek — feature a photo of Brennan with the message: “This psycho must be charged, tried, convicted — and hung for treason.”
