Responding to a blustery announcement from Donald Trump that he will be making an appearance at the U.S. Court of Appeals for a Tuesday hearing on his presidential immunity appeal, one former prosecutor warned the former president that he is on thin ice.

Just after midnight Monday, Trump took to his Truth Social platform to announce, "I will be attending the the (sic) Federal Appeals Court Arguments on Presidential Immunity in Washington, D.C., on Tuesday. Of course I was entitled, as President of the United States and Commander in Chief, to Immunity. I wasn’t campaigning, the Election was long over. I was looking for voter fraud, and finding it, which is my obligation to do, and otherwise running running (sic) our Country."

Noting that the former president has been making a habit of holding impromptu press conferences outside Judge Arthur Engoron's courtroom to complain about being held accountable for committing financial fraud, former U.S. Attorney Joyce Vance alerted the former president those kinds of antics won't play well with the appeals court justices.

Added to that, she stated reports that Judge Tanya Chutkan was victimized with a swatting on Sunday night will surely set the stage for zero tolerance by the judges.

Taking to X, Vance wrote, "Courts of Appeals tend to frown on litigants holding press conferences on the courthouse steps. Especially if reports that trial Judge Tanya Chutkan was swatted last night are true, expect little tolerance for Trump shenanigans."
