In the lead-up to Vice President Sara Duterte's impeachment trial, concerns have emerged regarding the Senate's willingness to admit evidence gathered by the House of Representatives. Iloilo Representative Lorenz Defensor expressed that if the Senate were to block critical evidence, it would damage the reputation of the senator-judges and could lead to public discontent. Defensor emphasized that the impeachment process is intentionally designed to allow a broader interpretation of evidence rules, ensuring that the proceedings remain transparent and accountable to the public.

Prosecutors, including Batangas Representative Gerville Luistro, are optimistic that the impeachment court will accept the evidence presented during the trial. The prosecution team has prepared a list of witnesses and evidence, and they believe that any issues regarding admissibility will be resolved in the pre-trial phase.

Allegations against Duterte include misuse of confidential funds, with former aide Ramil Madriaga claiming that Duterte ordered cash deliveries amounting to approximately ₱30 million to ₱35 million. The Senate's history of not revealing key evidence during impeachment trials raises concerns about the potential for public protests, reminiscent of the backlash during former President Joseph Estrada's impeachment trial.
