Trump-appointed judge's impartiality questioned in Mar-a-Lago documents case.

Aileen Cannon, a Trump-appointed judge who has previously ruled in his favor, will oversee the trial of the former president on charges of mishandling classified information. Experts believe the trial could influence public trust in the fairness of the court system. Cannon will determine how quickly the case goes to trial, oversee the selection of jurors, and determine what evidence can be presented to the jury. The defense team is expected to file motions to exclude evidence from Trump's former lawyer, Evan Corcoran, which could critically hobble the Justice Department's case if granted. Cannon's past rulings have raised concerns about her impartiality, and some legal experts have called for a review of how she was assigned to the case. The trial could deepen public doubts and partisan divisions, or affirm the ideal that the powerful should be held accountable for their actions.
