An eleventh suspicious package addressed to US Senator Cory Booker was found on Friday morning, as federal authorities investigate the bombs sent to prominent Democrats and critics of US President Donald Trump.
The latest package was found at a mail sorting facility in Florida and was addressed to the Democratic senator from New Jersey, the FBI said on Twitter. New York City police were investigating a suspicious package at a postal facility on Friday morning as well, authorities said.
A local police bomb squad and canine units joined federal investigators on Thursday to examine a sprawling US mail distribution center at Opa-Locka, northwest of Miami, Miami-Dade County police said.
US Homeland Security Secretary Kirstjen Nielsen said that Florida appeared to be the starting point for at least some of the bomb shipments.
“Some of the packages went through the mail. They originated, some of them, from Florida,” she said during an interview with Fox News Channel on Thursday. “I am confident that this person or people will be brought to justice.”
Authorities called the parcel bombs an act of terrorism. They were sent less than two weeks before national elections that could alter the balance of power in Washington.
No one has claimed responsibility for the bombs, and the public was asked to report any tips.
All the people targeted were frequently maligned by right-wing critics. They included Democratic Party donor George Soros, former President Barack Obama, former Vice President Joe Biden, and former Secretary of State and presidential candidate Hillary Clinton.
