(CNN)The man accused of sending mail bombs to prominent Democrats last fall is expected to plead guilty in federal court next week, according to the US Attorney's Office for the Southern District of New York.
CNN's New York bureau was evacuated in October after a package with an explosive device, addressed to former CIA Director John Brennan, was discovered, officials said.
None of the devices detonated and no one was injured.
Sayoc was previously expected to appear in court next week for a pretrial hearing, but is now scheduled for a plea hearing, prosecutors said. The trial was expected to begin in July.
Sayoc faces a series of charges, including five counts of use of a weapon of mass destruction and five counts of interstate transportation and receipt of explosives. It's not clear what charges the plea will involve.
CNN was reaching out Friday to a defense attorney for comment.
