Frequently, protesters will seek to supplement their complaints after the initial GAO protest submission. When protesters raise multiple rounds for complaint, the Government Accountability Office (GAO) will be guided by its bid protest regulations on timeliness under 4 C.F.R. § 21.2. These regulations do not contemplate “[t]he piecemeal presentation or development of protest issues.” Curtis Center Ltd. Partnership—Reconsideration, Comp. Gen. Dec. B-257863.3, 95-1 CPD 147.
