The Florida man accused of sending pipe bombs to prominent critics of President Trump pleads not guilty to all 30 charges against him.

Cesar Sayoc entered the plea through his lawyer during his appearance in Manhattan federal court Thursday.       

He was arrested last month outside an auto parts store in Plantation, Florida. Authorities say he sent improvised explosive devices to several Democrats, critics of Trump, and CNN.

Some of the devices arrived here in the city. None of them exploded.

Prosecutors say they are still looking for surveillance videos linking Sayoc to the explosives.

The trial is set to begin July 15, 2019. If convicted, Sayoc could face a mandatory life sentence.
