Prosecutors in NY plan to argue Tuesday that Sayoc should continue to be held without bail pending trial, due to being a flight risk and posing a danger to the public.
Sayoc, 56, is scheduled for a 10 a.m. appearance before Manhattan U.S. Magistrate Judge Robert Lehrburger, authorities said Monday.
Authorities arrested Cesar Sayoc, a staunch Trump supporter, in Plantation, Florida, on October 26 in connection with the series of mail bombs ― none of which detonated. Sayoc was charged with the mailing of explosives, threatening a former president, making threatening interstate communications and assaulting federal officers, according to The Independent.
Sayoc was due to arrive in NY on Monday after waiving his right to a bond hearing in Miami on Friday.
The suspect was living in a van plastered with pro-Trump and anti-Democrat stickers when he was arrested at an auto store in Plantation, Florida.
Sayoc is accused of sending 15 devices fashioned like pipe bombs to targets including former President Barack Obama, former Secretary of State Hillary Clinton, former Vice President Joe Biden, former Central Intelligence Agency director John Brennan, billionaire investor-philanthropist Georg Soros, actor Robert De Niro, CNN and others.
"Yet another suspicious package, addressed to CNN's Atlanta office, was intercepted. three days after Sayoc's arrest".
Assistant prosecutors to Manhattan U.S. Attorney Geoffrey Berman confirmed another explosive device Sayoc allegedly mailed to California-based billionaire hedge fund manager Thomas Steyer was discovered Friday, USA Today reported.
None of the devices exploded, and no one was injured in the pipe bomb scare.
While Sayoc's attorneys have not commented on his mental health, his mother wrote a letter to ABC News saying he has suffered from mental illness for years.
"This is not how I raised him or my children", Madeline Sayoc wrote in her letter.
