The Department of Homeland Security (DHS) said Tuesday morning it is investigating information it had recently received regarding a threat to the inaugural ceremonies.

"The FBI, the Department of Homeland Security (including the [United States Secret Service]) and the intelligence community are coordinating with other law enforcement authorities to investigate and analyze recently received information about a potential threat on Inauguration Day," a Department of Homeland Security spokesman said. "This information is of limited specificity and uncertain credibility.

DHS said that President-elect Obama's transition team had been briefed about the nature of the threat, and had been "fully integrated into the process."

While DHS encouraged citizens attending the inauguration to go about their normal plans, they also asked those who came to be patient and vigilant.

DHS also said there was an "unprecedented level of security" at the inauguration, and said it was constantly reviewing its security measures as they receive additional information about threats.
