A fan of US President Donald Trump who mailed parcel bombs to prominent Democratic figures last October was set to appear in court Thursday, where he was expected to plead guilty to some of the 30 charges against him. Cesar Sayoc, 57, who was arrested in Florida on October 26 following a massive manhunt, was due in federal court in New York at 4:00 p.m. Although it was not known which charges he would plead guilty to, all relate to the 16 package bombs he is accused of mailing from a Florida post office to several well-known people who oppose Trump, as well as the Manhattan offices of CNN. He previously pleaded not guilty to all counts. The packages’ intended recipients included billionaire philanthropist George Soros, former secretary of state Hillary Clinton, former president Barack Obama, former vice president Joe Biden, actor Robert De Niro and several Democratic lawmakers, including 2020 presidential hopefuls Cory Booker and Kamala Harris. None of the packages exploded or even reached their targets and authorities questioned the actual danger they posed. But by targeting Democrats, Sayoc — who also goes by the alias Cesar Altieri and was identified by DNA recovered from the packages — helped contribute to heightened tensions during the US midterm election campaign season. Sayoc’s partial guilty plea Thursday could help mitigate the severity of a sentence if he is convicted on all counts. As his trial loomed, information from Sayoc’s past began to filter into the public sphere, fueling the debate about extremism in the age of Trump and social media — a debate that grew more urgent as 11 people were shot dead at a Pittsburgh synagogue later in October. Estranged from his family and in financial distress, Sayoc lived in a white van plastered in stickers proclaiming his admiration for the US president. His criminal record dates back to 1991, peppered with convictions for theft, fraud, violence and a threat to bomb his electric utility company. A former strip club manager and an adept bodybuilder and martial arts practitioner, Sayoc discovered a passion for Trump just as his political star was rising. His social media posts took a politically radical turn: he’s seen wearing a “Make America Great Again” hat, sharing pro-Trump images and posting articles from ultra-conservative and conspiracy-driven websites such as Infowars and Breitbart.
