"I turn to some of the most trusted, skilled and intelligent minds that the Republic has to offer. This is the team that will help me forge a peaceful end to the current dispute."
The committee was often a target of criticism prior to the Battle of Geonosis, with claims of being a "Shadow government" and an attempt by Palpatine to prevent the passing of the Military Creation Act. The Committee itself was split between pro-military and pro-diplomacy. Prior to the Battle of Geonosis, Havriso Looruya was exposed as having Separatist ties by Onaconda Farr (Savareen sector), who replaced him on the Committee; also, upon the assassination of Aks Moe, Moe was replaced by Ask Aak (Malastare).
Interestingly, most members of the Loyalist Committee were vocal opponents of Palpatine's reformations, suggesting the Committee may really have been a means for Palpatine to keep an eye on potential enemies. The Committee found itself increasingly at odds with the Chancellor's increasing executive powers, and often had trouble gaining an audience with him. Many of the Committee members were amongst the Delegation of 2000, with Amidala as their spokesman, seeking to persuade the Chancellor to surrender his emergency powers and return power to the Senate: the Delegation especially opposed the creation of the office of Moff, which effectively stripped the Senate of real power.
When the Clone Wars ended and the New Order was declared, the Loyalist Committee was almost certainly dissolved. At least two of its members, Bail Organa and Mon Mothma, went on to become leaders of the Alliance to Restore the Republic.
