According to PPP prediction market monitoring, Donald Trump's odds of announcing a new White House press secretary before Sept. 11 — next Friday — have fallen to 13% on Polymarket, down 10% in the past 24 hours. The decline comes with growing attention to staff turnover in Trump's orbit ahead of the U.S. midterm elections. Over the last month, Trump has lost his White House press secretary, chief legal counsel, a key national security adviser and the official overseeing congressional affairs. Sources say more senior aides are weighing exits in the coming months. On the replacement front, White House deputy press secretary Anna Kelly now leads the field, with a 24% probability that Trump selects her next, overtaking previous front-runner Scott Jennings. Alina Habba — senior adviser to the U.S. attorney general and the former lead defense lawyer in Trump's hush-money case — has climbed to third, surpassing fellow contender Margo Martin.
