A terror suspect accused of plotting to bomb a skyscraper in Dallas, Texas, is scheduled to plead guilty Wednesday.
Hosam Maher Husein Smadi, a 19-year-old Jordanian, will plead guilty to knowingly attempting to use a weapon of mass destruction, according to court documents in the case.
The plea is expected to be discussed at a federal court hearing Wednesday afternoon in Dallas. The charge carries a potential sentence of life in prison.
Smadi entered the United States illegally and lived in Texas where he tried to set off an explosive attached to a vehicle at the base of the 60-story Fountain Place office tower, federal officials said.
He drew authorities' scrutiny because of his violent posts on an extremist chat site, court papers said.
Undercover officers posing as members of an al Qaeda sleeper cell contacted Smadi and, after months of conversations, considered him to be a legitimate threat, authorities said.
Smadi said many times that he wanted to commit violent jihad and that he was a soldier of Osama bin Laden, prosecutors said.
Authorities said they have found no tie between Smadi and any terrorist group.
