Police in Washington Township in Northampton County say the FBI and local police took 44-year-old Jason Muzzicato into custody Friday morning. They say he faces federal charges. Authorities searched Muzzicato's home and his business, Bangor Motor Works, and say they found evidence at both locations tying him to the explosions. They did not provide specifics. Miller says the motive is unclear.
Two law enforcement officials, speaking to The Associated Press on condition of anonymity to discuss an ongoing investigation, said the device was crude but operational. It was addressed to former CIA Director John Brennan, who regularly appears as a television contributor and who has publicly clashed with Trump.
