A suspect has been arrested in Florida in connection with the rash of suspicious packages sent to prominent Democrats. A news conference is scheduled for 1:30 p.m. to provide more details about the arrest.

The Orlando Sentinel reports federal authorities have been combing the state of Florida for clues because they believe that's where the majority of packages originated.

At least one man “has been taken into custody for questioning.”  Sarah Isgur Flores, director of public affairs at the Department of Justice, confirmed the news on Twitter: “We can confirm one person is in custody,” Flores tweeted.

We don't yet have the suspects name nor do we know his role in the plot.

“Some of the packages went through the mail,” Homeland Security Secretary Kirstjen Nielsen told Fox News. “They originated, some of them, from Florida. I am confident that this person or people will be brought to justice.”

Several of the packages went through a U.S. postal facility in Opa-locka, Florida. The Miami-Dade County Police Department confirmed Thursday it was helping federal agents who were at the facility as part of the ongoing investigation.

The envelopes and packaging materials were being closely analyzed and likely contain a treasure trove of DNA information. Tiny bits of genetic material – traces of sweat, skin cells, saliva, hair or fingerprints – are typically used as a roadmap to the suspect’s door, investigators and bomb experts say.

Suspicious packages were mailed to former President Barack Obama, former Secretary of State Hillary Clinton, liberal billionaire George Soros, former Attorney General Eric Holder, former CIA Director John Brennan and California Democratic Rep. Maxine Waters.
