Bomb squads were called to a post office in Atlanta on Monday about a suspicious parcel, just hours before a court hearing for a Florida man accused of sending packages containing explosive material to prominent Democrats.

The FBI did not identify to whom the most recent package was addressed, but CNN President Jeff Zucker announced that a suspicious package addressed to the cable television network was intercepted Monday at an Atlanta post office.

Zucker said there was no imminent danger to the CNN Center. Another package was delivered to the cable network's New York offices last week, causing an evacuation.

The latest suspicious package comes just hours before a federal court hearing was to begin for Cesar Sayoc, 56, who faces five federal charges.

He is accused of sending bubble-wrapped manila envelopes to Democrats such as Barack Obama, Hillary Clinton and Joe Biden. The packages were intercepted from Delaware to California. At least some listed a return address of U.S. Debbie Wasserman Schultz, former chair of the Democratic National Committee.
