49 CFR Part 27 - Nondiscrimination on the Basis of Disability in Programs or Activities Receiving Federal Financial Assistance (with amendments issued through Aug. 2015)

(e) Intimidating and retaliatory acts prohibited. No employee or contractor of a recipient shall intimidate, threaten, coerce, or discriminate against any individual for the purpose of interfering with any right or privilege secured by section 504 of the Act or this part, or because the individual has made a complaint, testified, assisted, or participated in any manner in an investigation, hearing, or proceeding, under this part. The identity of complainants is kept confidential at their election during the conduct of any investigation, hearing or proceeding under this part. However, when such confidentiality is likely to hinder the investigation, the complainant will be advised for the purpose of waiving the privilege.
