Federal authorities made an arrest in southeastern Florida Friday morning in connection with a series of suspicious packages mailed to prominent Democrats and critics of President Trump. 

The suspect is a white man in his 50s who moved to Florida from New York. He has a previous history with law enforcement, including making terroristic threats, Fox News' Catherine Herridge reported.

Multiple sources identified the suspect to Fox News as Cesar Sayoc of Aventura, Florida.

The Department of Homeland Security has said there are no links to international terrorism. 

Several of the packages went through a U.S. postal facility in Opa-locka, which is less than 10 miles from Aventura, where the suspect resides.

Authorities could be seen taking away a white van, covered by a blue tarp, from a location in Plantation, Florida.

They later removed the tarp, revealing that the van is covered with an assortment of stickers, including what appear to be American flags and pro-Trump paraphernalia.

Earlier today, two more packages were discovered in Florida and New York, bringing the total to 12 this week. 

Previous suspicious packages were addressed 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.

Several of the packages contained what officials called a "potential explosive device," though none were found to be operational. Brennan's package was sent to CNN headquarters in New York, forcing the newsroom to evacuate on Wednesday morning.

A few more packages turned up on Thursday, addressed to former VP Joe Biden and to actor Robert De Niro's Manhattan restaurant.
