District of Columbia officials expect between 500,000 and 700,000 people to attend the presidential inauguration on Monday. That's fewer than the 600,000 to 800,000 people initially anticipated.
The district's homeland security director, Chris Geldart, says the lowered crowd estimate isn't changing any of the security preparations or planning for the event.
More than 2,000 police officers from across the country were sworn in as deputy U.S. marshals during a training session Sunday at American University. The oath authorizes them to work security for the event.
Authorities haven't revealed the precise number of law enforcement officers working Monday, but a Metropolitan Police Department spokesman says about 2,600 officers have arrived from out of town. That will supplement the department's roughly 3,800 officers, as well as agents from the Secret Service, the FBI and other agencies.
