The man accused of mailing pipe bombs to critics of President Trump is expected to plead guilty next week in federal court in Manhattan, the court’s docket shows.

The defendant, Cesar A. Sayoc Jr., a fervent Trump supporter, sent homemade bombs created with PVC pipe and glass shards to prominent Democrats, including Hillary Clinton and former President Barack Obama, as well as to CNN and the actor Robert DeNiro, the authorities said.

The court’s docket entry states only that there is a plea scheduled for Thursday, but it does not indicate what charges Mr. Sayoc will plead guilty to. He was indicted in November on 30 federal charges, including using a weapon of mass destruction and interstate transportation of an explosive.
