Sayoc, a 56-year-old former stripper and pizza delivery driver who lived in a white van festooned with right-wing political images supporting Trump and attacking his critics, was arrested in Florida on October 26 following an intense manhunt.
The registered Republican, who has a criminal history and reported past as a stripper, was subsequently flown to NY and appeared in a Manhattan court earlier this week, before the 30-count indictment was unveiled. The scare heightened tensions before the crucial midterm elections, but he was arrested within days.
The charges include five counts of use of a weapon of mass destruction for each pipe bomb mailed to and intercepted in the NY area, targeting billionaire liberal donor George Soros, former Democratic presidential nominee Hillary Clinton, actor Robert de Niro, former CIA director John Brennan and former intelligence chief James Clapper. Sayoc was also accused of threatening his intended targets and violating federal law by mailing the devices through the U.S. Postal Service.
The charges said he aimed to "kill, injure and intimidate an individual and unlawfully to damage and destroy a building, vehicle, and other real and person property".
A message left with Sayoc's lawyer was not immediately returned.
None of the devices exploded before being intercepted, and no one has been injured.
Sayoc appeared in NY earlier this week. He was held without bail. Sayoc lives in Fort Lauderdale but was arrested in Plantation, a suburb of Miami.
In the indictment, prosecutors noted that an improvised explosive mailed to former Democratic presidential nominee Hillary Clinton in Chappaqua, New York, contained a picture of Clinton and members of her family marked with a red "X". The indictment said others received similarly marked pictures. Kamala Harris and Cory Booker, among others, last month.
The package sent to Biden was found at a postal facility in New Castle, Delaware, while the package sent to De Niro's Manhattan office was called in by a building worker who was anxious about a suspicious package that arrived days earlier.
His fingerprint allegedly was picked up on two of the envelopes he sent.
The case was randomly assigned to U.S. District Judge Jed S. Rakoff. An arraignment hearing for Sayoc has yet to be announced. At that time, he will enter a plea.
