A Signal Mountain man who admitted plotting to kill Muslims in a town in Upstate New York to show that it was "a true threat" is to undergo an evaluation at a facility in Lexington, Ky.
Robert Doggart will be tested at the Federal Medical Center.
Also, Doggart is facing new charges after a superseding indictment was issued this week.
He is charged with solicitation to commit a civil rights violation, solicitation to commit arson of a building, and two counts of threat in interstate commerce.
Doggart was earlier allowed to be on house arrest.
Prosecutors say Doggart, a former candidate for Congress in the 4th District, had focused on the Muslim community of Islamberg outside Hancock, N.Y., and tried to recruit "gunners" who would go with him to kill individuals there and destroy several buildings, including a mosque and a school.
Prosecutors said the government had tapped Doggart's phone and listened to him discussing the plot with several individuals. They said Doggart also made Facebook posts about the plan.
Doggart is now represented by attorney Garth Best.
