(CNN)The last few months of 2018 saw an uptick in domestic terror arrests compared to some other quarters in recent years, a senior FBI official told CNN.
- Christopher Paul Hasson -- a Coast Guard lieutenant arrested last month on firearms and narcotics charges stemming from an FBI investigation that unearthed plans Hasson had for a widespread attack on prominent elected officials and several high-profile television anchors. His first appearance in federal court in Maryland was Monday for his arraignment, in which he pleaded not guilty to the four counts against him.
- Robert Gregory Bowers -- Tree of Life Synagogue shooting in a Pittsburgh neighborhood, which left 11 dead. He was charged in a superseding 63-count indictment in January. He was arraigned in federal court the following month and pleaded not guilty to the new hate crime charges. There is no date for the trial, but he's due in court by April 17 for a pre-trial motion.
- Cesar Sayoc -- Arrested in November after mailing multiple pipe bombs to high profile victims around the country. Sayoc has been indicted on 30 charges. A jury trial has been scheduled for July 15 and a pre-trial conference has been set for March 21.
- Four Rise Above Movement (RAM) Members -- Four Southern California men who were arrested in October in connection with traveling to political rallies across California, where they violently attacked counter-protesters, journalists and a police officer. One of the men charged, Robert Rundo, had been previously charged in a separate indictment out of Virginia for violent altercations at the Unite the Right Rally in August of 2017. The trial for the four men is set for July 9.
- Joseph Dibee -- One of two remaining FBI fugitives and domestic terrorism subjects linked to the FBI's long-running Operation BACKFIRE, who was apprehended in Cuba this past summer and returned to the US after 12 years on the run. His trial is set for May 14.
