CNN President Jeff Zucker says all mail to CNN has been screened offsite since last week, when a series of package bombs began appearing around the country.
CNN obtained a photo of the package, which appears to be identical to the ones sent last week to several prominent Democratic leaders and CNN's NY offices. The third, suspected, explosive device was addressed to CNN's Atlanta offices.
Sayoc was arrested last Friday in Florida, after more than a dozen bombs had been intercepted across the country; none of them went off. Sayoc, who is facing federal charges, is being tried in the U.S. Southern District of NY.
The official said investigators are scrutinizing the social media posts of 56-year-old Cesar Sayoc, who is due to appear in federal court Monday. It was addressed to Time Warner Center. It is unclear from where this latest package originated.
If America hoped President Donald Trump would scale back his attacks on his perceived opponents after they started finding in bombs in their mail, we were disappointed.
"There is no imminent danger to the CNN Center", Zucker said in the statement. The post office was evacuated and surrounding streets in downtown Atlanta were shut down.
The packages sent to CNN's New York City offices last week contained pipe bomb-like devices.
The news comes five days after a pipe bomb was mailed to CNN's NY headquarters.
The FBI did not identify to whom the package was addressed.
The Atlanta Police Department said officers responded to the call about the package at 9:38 a.m. He's facing charges for five federal crimes, including the illegal mailing of explosives. Authorities have not yet made any formal connections to the other packages.
Brooklyn-born Sayoc is being prosecuted in NY, so his Florida hearing will likely be brief and process-oriented.
