NBC News: Man arrested in Florida will face charges in connection with pipe bomb packages

NBC News reports a man who was arrested in Florida will face charges in connection with pipe bomb packages that were mailed across the US. 

UPDATE: NBC News reports 56-year-old Cesar Sayoc Jr., a Florida resident, is the suspect arrested in Florida in connection with wave of pipe bomb packages.

The Associated Press reports Justice Department spokeswoman Sarah Isgur Flores said authorities planned to announce more information at a press conference.

Earlier Friday, authorities said suspicious packages addressed to New Jersey Sen. Cory Booker and former National Intelligence Director James Clapper -- both similar to those containing pipe bombs sent to other prominent critics of President Donald Trump -- had been intercepted.

Twelve such discoveries have been made so far. Officials have been working to find a culprit and possible motive while it's unclear if new packages were being sent or simply surfacing after a period in mail system.
