The Senate recently held a hearing on the performance (or lack thereof) of the MSPRC. The Senate Homeland Security and Government Affairs Committee, Contracting Oversight Subcommittee, held a two hour hearing regarding CMS's contracting activities with the MSPRC. Chairwoman Claire McCaskill (D-Mo.) and Ranking Member Scott Brown (R-Ma.) both criticized CMS for allowing the MSPRC to be so unresponsive and for complicating the MSP process beyond reason.

The GAO also issued a report regarding CMS contractors. On page 53 of the report, it indicates that the MSPRC is not hitting many of its contracting benchmarks.
