President Trump has signed into law (P.L. 116-30) a bill to generally require that federal buildings that are open to the public and that contain a public restroom provide a lactation room, other than a bathroom, that is hygienic and is available for use by members of the public to express milk.
The lactation room must be shielded from public view, be free from intrusion, and contain a chair, a working surface, and an electrical outlet (if the building already has electricity).
Under language in annual appropriations laws, federal buildings already generally must have such rooms available for their own employees meeting similar standards.
A building could be excluded from the widened requirement on grounds that it does not contain a lactation room for employees and that the cost of repurposing existing space or adding new space would not be reasonable.
