In order to allow for the installation of scaffolding and floor, statuary, and artwork protection in conjunction with the Dome Restoration Project, the Rotunda of the Capitol will be closed from Monday, July 27 through Monday, September 7. While the Rotunda is unavailable for tours, an alternate tour route will be provided. The Capitol Visitor Center is open during the closure of the Rotunda and will offer special activities which do not require advance reservations. You can also download our new U.S. Capitol Rotunda app.

Keeping Secrets

In Congress, one person may have reasons to keep information private, while another has equally compelling reasons to make it public. In 1844, as the volatile issue of slavery inflamed emotions, Senator Benjamin Tappan of Ohio gave a secret treaty to a journalist. He wanted to publicize sections of the treaty that would allow slavery in Texas.

The Senate censured Tappan and threatened to expel future members who "leaked," or revealed, secrets.

Four years later, someone in the Senate gave the still-secret Treaty of Guadalupe Hidalgo, ending the Mexican War, to New York Herald reporter John Nugent. Determined to make good on its threat to enforce secrecy, the Senate ordered Nugent imprisoned in the Capitol until he named his source. Nugent refused. A frustrated Senate eventually released the reporter without discovering his source.
