Although the homemade pipe bombs have not exploded, authorities say they are treating them as "live devices," not "hoax devices," New York City Police Commissioner James O'Neill said Thursday.
Authorities who have discovered the parcels around the country — in New York, outside Washington, D.C., in Florida and in Los Angeles — are sending them to the FBI Laboratory in Quantico, Virginia, for examination there.

At least one of the packages passed through a large U.S. mail sorting facility in Opa-locka, Florida, near Miami, according to multiple reports.
The Miami Herald, citing a federal law enforcement official familiar with the investigation, reports that the package sent from the facility is likely the one that ended up on Wednesday at the South Florida office of U.S. Rep. Debbie Wasserman Schultz.
That package was originally sent to the office of former U.S. Attorney General Eric Holder. It was not delivered and was instead sent to the labeled return address — listed as Wasserman Schultz's office.
Before the package arrived there, the Herald reports it was rerouted through the Opa-locka mail sorting facility.
Federal agents and the Miami-Dade County Police Department searched the facility on Thursday night, according to reports from the Herald, Reuters and The Associated Press. No potentially explosive devices were found, according to reports.
"A search of a postal database suggested at least some may have been mailed from Florida," the AP reports.
Hundreds of thousands of packages pour into the facility every day — it's the size of five football fields, the Herald reports. Miami-Dade Police Department specialists worked at the mail center on Friday morning, the agency said.
The packages began to show up on Monday, starting with billionaire George Soros, a major donor to Democrats and Democratic causes.
In addition to Steyer, Harris, Booker, Clapper and former CIA Director John Brennan, one package has been addressed to former President Barack Obama, two to former Vice President Joe Biden, one to former Secretary of State Hillary Clinton, one to former Attorney General Eric Holder and two to Rep. Maxine Waters, D-Calif. One was also addressed to the actor Robert De Niro, a harsh Trump critic.
De Niro included a political callout in his statement about the packages on Friday morning.
"I thank God no one's been hurt, and I thank the brave and resourceful security and law enforcement people for protecting us," he said. "There's something more powerful than bombs, and that's your vote. People must vote!"
Trump sounded the same note when he addressed the parcel attacks Friday morning on Twitter.
