Law enforcement is investigating after someone threatened to blow up the Grand Traverse County Republican Headquarters. Deputies say it happened around 3:15 p.m. Wednesday at the GOP headquarters in Cherryland Mall. Employees say the suspect had a sign that said "Trump is Satan" and started going off on a rant about Republicans. When he was asked to leave, employees say he made a statement about blowing the place up and took off. Investigators brought in a bomb sniffing dog as a precautionary measure and deemed the place safe just before 5:00 p.m.
