Congressional Accountability Act Enhancement Act This bill extends the liability of Members of Congress for employment discrimination settlements and awards and expands certain employment protections for congressional employees. Current law requires that a Member who commits an act of harassment in violation of employment-based civil rights protections must reimburse the Treasury for amounts paid as settlements or awards resulting from the act. This bill also requires that Members reimburse the Treasury for amounts paid resulting from any unlawful discrimination and related retaliation. Additionally, the bill grants congressional employees a 10-day period to amend a filing alleging employment discrimination if the hearing officer determines the initial filing failed to state a claim for which relief could be granted. The bill also allows the Office of Employee Advocacy to continue to assist a congressional employee with investigations and proceedings related to a claim of workplace discrimination even after the employee begins federal court proceedings.
