President Donald Trump on October 26. praised law enforcement efforts to capture the suspect.
President Jeff Zucker said the package was similar in appearance to those mailed to the network last week in New York City. It's possible the suspect sent some other package bound for Los Angeles but official don't believe it's that many, said the source, who spoke on the condition of anonymity.
The official said authorities had recovered soldering equipment, a printer, and stamps after arresting Sayoc.
Two earlier bombs were also sent to CNN in the past week.
Although authorities did not immediately say who might be responsible for the most recent package to CNN, the Federal Bureau of Investigation said it believes the package discovered Monday is similar to those that Sayoc is accused of sending.
Sayoc made his first, largely procedural court appearance on Monday in Miami.
Cesar Sayoc, a 56-year-old Aventura, Florida, resident, was arrested on Friday in connection to the packages. He's accused of sending more than a dozen packages to George Soros, Hillary Clinton, former President Barack Obama, Rep. Maxine Waters (D-Calif.), and others.
Spokesman Kevin Rowson said via email that the agency had been notified by the U.S. Postal Inspection Service of a suspicious package that arrived at 400 Pryor Street in downtown Atlanta, which is the address of a post office. A judge set another hearing for Friday on whether to grant bail to Sayoc and to discuss when he will be sent from Miami to NY, where five federal charges were filed.
Sayoc is scheduled to appear in court again Friday and will remain in custody at least until then.
"We don't know what they have yet".
Flanked by his newly retained three private attorneys, Dan Aaronson, James Scott Benjamin and Peter Patanzo, Sayoc appeared in a federal courthouse in Miami Monday afternoon.
Balsamo reported from Washington.
"This morning, another suspicious package addressed to CNN was intercepted at an Atlanta post office".
Authorities haven't said yet whether the package found Monday is linked to the other packages.
Authorities say Sayoc faces more than 50 years in prison if convicted on all charges related to pipe bombs sent to political figures across the country.
