Law enforcement officials are reportedly seeking out a package addressed to former Vice President Joe Biden because of similarities it has to suspicious packages sent to a number of other Democratic officials this week.
CNN's Jim Sciutto cited two law enforcement officials with the development Wednesday evening.
NBC News contributing correspondent Jonathan Dienst said on MSNBC that law enforcement officials are concerned that a potential package addressed to Biden was sent to the wrong address and therefore shipped to an office of Rep. Debbie Wasserman Schultz in Florida because that address appeared on the return label. He added that information from that U.S. Postal Service indicated that the package is out somewhere.
An array of Trump critics around the country were sent potentially explosive devices this week, including former President Barack Obama, former Secretary of State Hillary Clinton, former Attorney General Eric Holder, California Rep. Maxine Waters, and liberal billionaire philanthropist George Soros. Another package was sent to ex-CIA Director John Brennan at CNN's offices in New York City.
The potentially explosive devices included in these packages, sent in manila envelopes with a return address to Wasserman Schultz's office, are being examined by the FBI.
Earlier in the day it was reported that the package addressed to Holder was sent to the wrong address and therefore sent to Wasserman Schultz's office.
Authorities have yet to say they have a suspect.
"This country has to come together. This division, this hatred, this ugliness has to end," Biden tweeted earlier in the day.
