Cesar Sayoc pleaded guilty in Manhattan federal court Thursday to dozens of felony charges stemming from 16 explosive devices intended for high-profile liberal public figures, including former President Barack Obama and former presidential candidate Hillary Clinton.

Sayoc initially pleaded not guilty in November 2018 to charges brought by the office of U.S. Attorney Geoffrey Berman of the Southern District of New York.

“For five days in October 2018, Cesar Sayoc rained terror across the country, sending high-ranking officials and former elected leaders explosive packages through the mail,” Berman said in a statement. “Thankfully no one was hurt by these dangerous devices, but his actions left an air of fear and divisiveness in their wake. Sayoc has taken responsibility for his crimes, and will soon be sentenced to significant time in prison.”
