A California man was sentenced to 25 years in prison after plotting to detonate an incendiary device at a political rally in Long Beach.

Mark Steven Domingo, 28, of Reseda was found guilty on one count of providing material support to terrorists, along with one count of attempting to use a weapon of mass destruction, according to a statement from the Department of Justice. Domingo, who had been found guilty in August, had intended to use the device to bomb a white supremacist political rally.
