Is smoking allowed in Federal buildings?
Executive Order 13058
, "Protecting Federal Employees and the Public from Exposure to Tobacco Smoke in the Federal Workplace," bans smoking in all Executive Branch facilities, all interior space owned, rented, or leased space by the Executive Branch of the Federal government. There are certain excepted spaces, which include: The 118th Congress
This makes the US Capitol one of a handful of places in Washington, DC, and among the few remaining office buildings in the country where smoking is still allowed inside. Despite efforts going back more than 150 years to prohibit tobacco from the building, smoking is still allowed in members’ offices.
The Capitol, and the surrounding congressional office buildings, are federal property but operate independently of other government buildings and many rules — including those about smoking and pandemic procedures — are at the discretion of House and Senate leadership.
This says all you need to know about GOP priorities.
