The suspect's name is Cesar Sayoc Jr., NBC News and the Miami Herald reported, citing law-enforcement sources.

Federal authorities have arrested a man in Florida in connection with a series of attempted attacks on top Democrats and other public figures over the course of the week.

The suspect is Cesar Sayoc Jr., 56, from Aventura, Florida, NBC News and the Miami Herald reported, citing law-enforcement sources.

Sayoc was arrested around 10 a.m. ET on Friday at an AutoZone in Plantation, Florida, and is being questioned by FBI agents with the Joint Terrorism Task Force, according to reports.

President Donald Trump confirmed that a suspect was in custody. He said the suspect would be prosecuted "to the fullest extent of the law."

A spokeswoman for the Department of Justice also confirmed that a suspect was in custody and said a press conference was scheduled for 2:30 p.m.

Sayoc is expected to face charges in connection with the suspicious packages.

Sayoc, a registered Republican, has an extensive criminal history, including a 2002 arrest on charges that he made a bomb threat, according to reports from The New York Times and The Washington Post.

It's not clear whether anyone else may have been involved in the attempted attacks.

Police in Plantation also towed a van that appears to be connected to the arrest, according to reports.

At least 14 suspicious packages containing what authorities described as explosive devices have been intercepted since Monday. All were addressed or sent to top Democrats and other public figures whom Trump has vocally attacked and who've often been critical of the president.

So far, packages have been sent or addressed to former President Barack Obama, former Secretary of State Hillary Clinton, former CIA Director John Brennan, former Attorney General Eric Holder, Democratic Rep. Maxine Waters, former Vice President Joe Biden, the actor Robert De Niro, Democratic Sen. Cory Booker, former Director of National Intelligence James Clapper, Democratic Sen. Kamala Harris, Democratic donor Tom Steyer, and the billionaire Democratic donor George Soros.

Debra Gureghian, the general manager of the Fort Lauderdale pizzeria where Sayoc had a brief stint as a truck driver, told The Washington Post that the best word to describe him was "crazed."

Gureghian said that Sayoc's comments about LGBTQ people and African-Americans worried his coworkers..

“He was very angry, and angry at the world, at blacks, Jews, gays,” Gureghian told The Post. “He always talked about ‘if I had complete autonomy, none of these gays or these blacks would survive.’ He never said he would kill them or murder them or bomb them, he just said, ‘If I had complete autonomy the gays, the black and Jews would not survive.’ He was very, very strange.”
