Ibraheem Ahmed Al Bayati made an initial court appearance on Tuesday in thefederal court in Houston.
Mr Al Bayati, 19, was accused by federal authorities of joining a university lecture on Zoom on September 2 and interrupting it by saying “what does any of this have to do with the fact that UH is about to get bombed in a few days?”
Mr Al Bayati, who identified himself as Abu Qital al Jihadi al Mansur on the call, was also accused of uttering an Arabic phrase that means the “Islamic State will remain”, according to a criminal complaint.
Investigators allege his discussion about the “Islamic State” was a reference to the terrorist organisation.
After Mr Al Bayati repeated the phrase, he left the call to the gasps of students, according to the criminal complaint.
He was arrested on Friday. Court records did not list an attorney for him.
Mr Al Bayati, a UScitizen who lives in Richmond, located about 30 miles (48km) southwest of Houston, told investigators the incident was a joke devised by him and a friend, according to the complaint.
Authorities also accuse Mr Al Bayati of being a recruiter for Islamic State.
Mr Al Bayati has been charged with making threats or conveying false information to destroy by means of fire or explosives and making a threat over interstate commerce.
If convicted, Mr Al Bayati faces up to 10 years in prison.
