Update: Christopher Cornell's hearing dates have been canceled until a telephone conference on April 27.
Tri-State terror suspect Christopher Cornell is expected in federal court for a pre-trial hearing Tuesday.
The 20 year-old Oak Hills High School graduate has pleaded guilty to three charges, including attempted murder of government officials, solicitation to commit a violent crime and possession of firearms in the furtherance of attempted violence.
He is accused of scheming with a confidential informant to build and detonate pipe bombs at or near the U.S. Capitol and then shoot employees inside the federal building.
The FBI arrested him based on comments they say he made on social media as well as online conversations with a source indicating he want to quote "wage jihad."
According to court documents, Cornell created a Twitter account under the alias Raheel Mahrus Ubaydah last summer. That's where he allegedly posted videos and statements supporting ISIS and violent jihad in North Carolina.
Cornell's trial scheduled to start March 2.
If found guilty, two of the charges carry 20 year-sentences and one lifetime imprisonment.
