H.R. 9835 — Congressional Oversight and Agency Access Act

This section grants every Member of Congress and congressional staff member access to any public building during regular business hours, with immediate access during public meetings and access within 24 hours outside regular hours upon request. It requires staff to be accompanied by the employing Member and to display valid identification, applies these rights during declared emergencies even when public access is restricted, and gives committee members (or those with Chair or Ranking Member consent) access within 24 hours to areas requiring security clearance. It also bars temporary building modifications that would limit congressional observation.
