White House press secretary Katie Zacharia faced criticism and speculation about her future after a roughly 14-minute debut Tuesday in which she relied heavily on prepared remarks and took questions from just three outlets. President Donald Trump nevertheless praised her performance, offering public support as prediction-market traders began wagering on her departure.

Zacharia's first appearance behind the podium also delivered consequential personnel news: the White House had asked Kimberly Guilfoyle, the U.S. ambassador to Greece, to resign. Reuters reported that the request followed allegations of misconduct, which Guilfoyle denied.

"She has been a wonderful asset to the team, and we wish her well," Zacharia said, without explaining the decision further.

The briefing's short duration and tightly limited questioning quickly drew attention. Zacharia called on Breitbart News, Fox News and the Daily Mail after outlining what she described as the administration's accomplishments.

"President Trump is fighting and delivering for American workers every minute of every day," she said.

The Associated Press described Zacharia as appearing nervous and stumbling over some words. While discussing family arrangements for her new position, the mother of four briefly referred to her husband as "my president" before correcting herself.

Trump offered a favorable assessment afterward, saying she had been "very good." White House Communications Director Steven Cheung called the appearance a "tremendous start" and defended her presentation of the administration's work.

Those endorsements contrasted with anonymous criticism from people in and around the administration. The Independent quoted a former Trump official calling the briefing "a train wreck," while an unnamed White House official warned that Zacharia needed to improve quickly.

The latter assessment invoked Anthony Scaramucci, whose brief service as Trump's communications director in 2017 remains a shorthand for rapid White House turnover. Scaramucci held a different job from press secretary, and accounts describe his tenure as either 10 or 11 days, depending on how it is counted.

The comparison spread online. Criminal defense lawyer Scott Greenfield wrote on X: "What's the over/under that she doesn't last a Scaramucci?"

Scaramucci himself declined to join the mockery. Responding to journalist George Sisca's suggestion that he might welcome someone breaking his record, he wrote: "Not me. I hope she makes it."

Reported Polymarket prices Tuesday evening assigned an 8% probability to Zacharia leaving by the end of October and a 29% probability to departure by Dec. 31. Those figures reflect traders' positions at a particular moment, rather than evidence that Trump plans to remove her.

No departure has been announced, and the president's public comments supported her continued service. The anonymous warnings and market activity do not establish that a dismissal is under consideration.

Zacharia, 41, previously advised the company behind Truth Social and appeared as a conservative commentator on Fox News and Newsmax. She succeeded Karoline Leavitt, who left the press secretary position in late August; Vice President JD Vance and Todd Blanche were among the officials who handled briefings during the intervening period.
