WASHINGTON (CNN) – The Transportation Security Administration said Tuesday that Louisiana Sen. David Vitter "did not pose a security threat" when he set off an alarm at Dulles International Airport earlier this month.
"TSA worked with local partners to review the incident and determined the actions of the individual did not pose a security threat," TSA spokesman Greg Soule said in a statement. "The individual caused a door to alarm but did not proceed into a restricted area."
Soule noted that the "review of the incident is now complete."
On March 5, the Louisiana Republican arrived at his gate with 20 minutes to spare and reportedly lost his temper when he saw that the door to plane was already closed. When he tried to open the door himself, he set off an alarm and got into a heated argument with an airport employee.
The National Republican Senatorial Committee suggested that incident was blown out of proportion.
"From the moment this story first appeared in a Capitol Hill gossip column it sounded a lot like the Democrats when they talk about trying to defeat Senator Vitter next year – a lot of hype, a lot of rhetoric but behind it all, not a lot of substance or supporting facts," NRSC communications director Brian Walsh said in a statement. "Fortunately, the record has now been set straight."
Vitter is up for re-election in 2010, his first race since his involvement with the so-called "DC Madam" became public.
