The new interim U.S. Attorney for the Northern District of New York, appointed to the post by President Donald Trump, once called out President Joe Biden, President Barack Obama, and twice-failed presidential contender Hillary Clinton.

John A. Sarcone III, a lawyer in private practice in Westchester County, accused Biden of being a “traitor” and committing “treason” in a 2022 social media post.

After Biden tweeted on New Year’s Eve that year he was “ready to get things done,” Sarcone responded, “Traitor should be tried for treason. Worst person to occupy the White House.”

Sarcone once tweeted that Obama should be “the first illegal alien deported” while calling for Clinton to be jailed for treason.

Sarcone was allowed to be placed in his interim position without needing Senate confirmation. And while he does not have any prosecutorial experience, he has a lengthy track record as an attorney who has also worked for Trump’s campaigns.

When Sarcone was sworn in on Monday in Albany, he defended his limited prosecutorial experience by asserting in his speech that what truly defines a good prosecutor is “judgment.”

“I believe the prosecutorial power, and discretion,” he said, “is best entrusted to those with the full breadth of professional and life experiences, from which common sense, wisdom, and informed judgment emerge.” Sarcone said his priorities will include securing the border with Canada; ending “lawlessness and willful disregard” for federal laws; and fighting against public corruption, scams and consumer fraud.
