NEW ORLEANS (AP) — U.S. Sen. David Vitter didn’t pose a security threat when the Louisiana Republican set off a security alarm at Washington Dulles International Airport earlier this month, the Transportation Security Administration said Tuesday. A statement issued by TSA said Vitter triggered a door alarm but didn’t enter a restricted area of the airport. A TSA spokesman said the agency has closed its review of the incident, but he wouldn’t elaborate on the statement.–Contact The Daily Reveille’s news staff at [email protected]
