Due to a special Joint Meeting of Congress taking place in the Capitol on Wednesday, April 29, the U.S. Capitol will be closed to tours until approximately 12:30 p.m. on that day. The Capitol Visitor Center will remain open throughout the day, 8:30 a.m. to 4:30 p.m., and guided tours of the Capitol Visitor Center will be available while the Capitol is closed.

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.
