An FBI spokeswoman confirmed that an explosive device addressed to Booker’s New Jersey office was intercepted in Florida.
The package containing the explosive - an alleged pipe-bomb style device - was intercepted at a South Florida U.S. Postal Service center mail sorting facility in Opa-locka according to the spokesperson.
According to reports, the package - which was addressed to Booker's office in Camden is located at 2 Riverside Drive - is the now among the 11th and 12th packages sent by an alleged serial bomber.
Suspicious packages were also found in a New York post office addressed to former Director of National Intelligence James Clapper, a retired lieutenant general in the U.S. Air Force.
Officials say investigators are actively searching for the culprit and attempting to determine whether devices were intended to detonate or to strew fear just weeks before Election Day.
