Local and federal authorities have been combing postal facilities in Florida, New York and other parts of the U.S. to try to track down any additional packages that may have made their way through the U.S. Postal Service. The package addressed to Booker is the 11th such parcel discovered this week, mailed to Democratic politicians like the Obamas, the Clintons and Rep. Maxine Waters, as well as CNN’s New York City office and other individuals Trump has been critical of. All the other packages have contained a pipe bomb-type of explosive device and all have been intercepted before they detonated.

According to CNN, it was unclear what was in the package as of Friday morning, but the container resembled those that have been sent to other targeted victims this week. A similar package was also found Friday morning at a New York City postal facility.

The FBI confirmed in a tweet that it intercepted the package in Florida.
