“Because the jury isn’t sequestered, they may see this,” Wine-Banks said.

“He’s going out of his way to say things that were laudatory about this defendant, and it’s just simply inappropriate for a president of the United States to use a public means of communicating, which Twitter is.” Wine-Banks noted that a judge recently ruled that Trump’s Twitter account was a public forum, and therefore he’s not allowed to block users from viewing or commenting on his posts. Trump has also noted that he uses Twitter as a means of communicating directly with the American people.

“I think he’s using a public forum to send a message to the jury that he should not have his former campaign chair convicted of anything,” Wine-Banks said.
