The mystery surrounding the envelopes containing explosive devices that have been sent to prominent Democratic political and entertainment figures across the country grew more complex Friday, as authorities located another suspicious package addressed to Sen. Cory Booker (D-N.J.).
The package was found in a Florida mail facility, the FBI confirmed Friday, and reportedly featured an address in Camden, New Jersey, NBC News reported. It was similar in appearance to the 10 others recovered this week.
New York City police also cleared an area of midtown Manhattan Friday morning following reports of a suspicious package in a postal facility. The object inside appeared to be a pipe bomb, according to The Associated Press.
It was reportedly addressed to former Director of National Intelligence James Clapper at CNN’s New York office, the network said, where he is a contributor.
“This is definitely domestic terrorism,” Clapper told CNN Friday after learning he was a target. “No question about it in my mind.”
He added that he was relieved no one had been hurt, and that he was not surprised to find himself a target.
Packages containing potential bombs have been mailed this week to high-profile Democrats including Hillary and Bill Clinton, former President Barack Obama, former Vice President Joe Biden, Rep. Maxine Waters (D-Calif.), and former CIA Director John Brennan via CNN’s New York City offices. (Brennan is a contributor for NBC and MSNBC.)
Billionaire philanthropist George Soros, a prominent Democratic donor, received one earlier in the week. A New York City address connected to frequent Trump critic Robert De Niro also received a package Thursday morning.
All packages ― manila envelopes with bubble wrap lining ― listed Rep. Debbie Wasserman Schultz (D-Fla.), the former chairwoman of the Democratic National Committee, as the return sender.
Miami-Dade police said they joined federal teams in investigating the Opa-Locka postal facility as a “precautionary measure” on Thursday. Several of the packages passed through this facility, according to CNN and The New York Times.
Authorities have yet to share a motive, but the Department of Justice said one person had been taken into custody as of Friday morning. Law enforcement officials told the news outlet that some of this work includes forensic examinations and data analysis from cell towers, the Times said.
None of the suspected pipe bombs have detonated, but New York Police Commissioner James O’Neill said Thursday that authorities were treating them as “live devices.”
“This is something that should be taken seriously,” he said.
