We know that the package was intercepted at a postal facility in Atlanta.
Zucker announced that there is no imminent danger to the CNN Center.
Investigators and bomb squads were called to a post office in Atlanta on Monday about a suspicious package sent to CNN, the Federal Bureau of Investigation said Monday, just hours before a court hearing for a Florida man accused of sending packages containing explosive material to prominent Democrats. The package appears identical to the other packages authorities say were sent by pipe bomb suspect Cesar Sayoc, who was arrested on Friday.
Last week, two of the packages believed to be mailed by suspect Cesar Sayoc were addressed to CNN. The discovery of the package on October 24 forced the evacuation of Time Warner Center in Manhattan and sent its anchors out to the street in the Columbus Circle area to cover the chaotic scene. It spurred a five and a half hour long evacuation of the building. Another package was addressed to former Director of National Intelligence James Clapper, who does analysis for the network. It was found Friday morning at a post office six blocks away.
Several of the packages were routed through the U.S. Postal Service's Royal Palm Mail Processing Center in Opa-Locka, Fla. - a center that routes mail and packages sent from Miami-Dade County, where Sayoc was living at the time of his arrest. All mail is being screened off site. Authorities have not yet made any formal connections to the other packages.
On Monday, following the interception of the suspicious package in Atlanta, Zucker said the same protocol would have applied in that incident.
