The Secret Service said Tuesday it will use Twitter to disseminate information to the public and news organizations for the first time during this week’s Asia-Pacific Economic Cooperation meeting.

"It is a first for us," said agency spokesman Max Milien. "We’re trying to get up to speed with the social networking."

He said the agency would release its Twitter handle or account name later.

President Barack Obama is hosting the conference, which is bringing to Honolulu heads of state and other leaders from 21 member nations and economies including China, Japan, Russia and Australia.

The meeting is hosted by a different member each year. Last year it was held in Yokohama, Japan.

The Secret Service has also set up a communications hub in Honolulu where federal, state and local authorities can share information on traffic accidents, power failures or other problems that might come up during the meeting.

The Secret Service, Police and Fire departments, the Hawaii National Guard, utility companies and other organizations have representatives at the Multi-Agency Communications Center.

"It’s key to making a seamless event to go on for Hawaii," said Derek Verdeyen, deputy assistant director of the Secret Service and the center’s supervisor.

Asked about people who demonstrate during the event, Frank Montoya, special agent in charge of the Secret Service’s Honolulu office, said his agency wanted to protect the First Amendment rights of every American to express their opinions and protest freely.

"At the same time, as we’ve seen around the world in some of these demonstrations, there are individuals that want to cause trouble, that want to break the law," Montoya told reporters. "The effort, interagency essentially, is to identify those individuals and try to prevent them from destruction of property or, worse, hurting people."

Montoya said there were indications that some of the people he described were on Oahu. He said they weren’t doing anything of concern now, but authorities were "paying attention to who they are" and have investigations involving some of them.

The Associated Press and other journalists were given a tour of the communication center on the condition that they not disclose its precise location.

The Secret Service sets up similar facilities at large-scale events like G-8 and G-20 summits and the national conventions of the Republican and Democratic parties.
