A spirited questioning period followed Trimble's speech, with most questions focusing on the recent delays in de-armament by militants on both sides.
"I did everything I humanly could to achieve progress. We need to see other people deliver their side of the bargain too." Trimble said, answering a questioner's allegation that he has impeded the implementation of the peace agreement.
"That's not enough," an audience member responded.
Other audience members criticized Trimble for his continued membership in the Orange Order, an Irish Protestant organization alleged to be heavily anti-Catholic.
Audience member Tom A. Oakley said that although Trimble defended himself well while answering questions, he gave a partisan interpretation of the peace process.
"I think he was selective in his facts," Oakley said.
Oakley said he was most surprised at Trimble's admission that he barely spoke to Sinn Fein leader Gerry Adams during the peace negotiations.
"I honestly thought the peace process involved a lot more talking than that," Oakley said.
