A Michigan man was arrested after an FBI investigation, accused of threatening to travel to Atlanta to commit mass murder at CNN headquarters. 

According to federal court documents, 19 year-old Brandon Griesemer made 22 calls to CNN about a week ago. 

It began with claims of "fake news" and ended with threats of violence. 

Griesemer told a CNN operator, among other things, "Fake news. I'm coming to gun you all down." 

He then called again, saying "I'm smarter than you. More powerful than you. I have more guns than you. More manpower. Your cast is about to get gunned down in a matter of hours."   

Griesemer continued, "I am coming to Georgia right now to go to the CNN headquarters to f---ing gun every single last one of you." 

Investigators were able to trace the caller and stop him before he was able to carry out any of his violent desires.

He's now jailed on a $10,000 unsecured bond.

Griesemer is also accused of making derogatory comments regarding the Islamic Center in Ann Arbor in September of 2017.
