At an inauguration security briefing, the FBI said there is no credible threat at this point.
The U.S. Secret Service is coordinating the efforts of 42 federal and local law enforcement agencies -- including military, public works and transit -- at the Multi-Agency Communications Center in the D.C. suburbs.
At Tuesday's briefing, Debra Smith, the acting assistant director in charge of the FBI’s Washington field office, said that while there is no credible threat to the inauguration, they have marshaled all resources to continue to monitor security.
One of the goals at the MACC is to provide real-time security information to all agencies. The center has access to basically all traffic, transit and law enforcement cameras in the D.C. area.
Authorities noted that one of the problems at President Barack Obama’s first inauguration was people with tickets being turned away. This time, additional signage will be posted to help people know where they are supposed to go, and social media will be used to make sure that the inauguration is accessible.
"There's an immense focus on making sure people feel like they are here to enjoy an event and they can get in and out without, you know, security being overbearing," Metropolitan Police Department Chief Cathy Lanier said.
“There's over 500 pole-mounted signs that didn't even exist last time; 28 event locations that are also going to be staffed with way finders, so there's not just signs there; and then 10 banner signs, and we've also changed way the six entrances to the ticketed events are handled," U.S. Capitol Police Chief Kim Dine said.
At the Capitol and along the parade route, security has banned items including backpacks, camera bags, tripods, alcoholic beverages, signs, portable chairs, umbrellas, firearms, knives and explosives.
The MACC opens Sunday and will remain open through the conclusion of all inaugural events Tuesday.
