Failing to Respond to Agency Report Renders Protest Grounds Abandoned; GAO B-415571, Medical Staffing Solutions USA

Protest arguing the awardee lacked past performance relevant to the procurement is dismissed, where the protester abandoned these grounds when it failed to rebut the agency’s response to the allegation; and protest challenging the rating assigned to the awardee’s past performance and the agency’s best value tradeoff is denied, where the allegations were untimely raised and did not relate to the original protest grounds.
