Gilberton, Penn., Police Chief Mark Kessler made the news last week for threatening on YouTube to shoot "libtards."
As the video went viral, Gilberton mayor’s office originally said that Kessler would not be disciplined.
The borough council in Gilberton, however, decided to suspended Kessler on Thursday.
The council said he used "borough property for non-borough purposes without prior borough permission" while shooting his YouTube videos.
Kessler was suspended without pay for 30 days.
Kessler's council meeting, according to CNN, drew thousands of gun rights activists.
Throughout the day, crowds of heavily armed protesters assembled outside of the meeting.
Mayor Mary Lou Hannon said that she still supports Kessler's right to free speech.
Aside from his now-viral YouTube videos, Kessler was also criticized for organizing a "volunteer group" that resembled a militia.
Kessler wrote on his website that local authorities were conspiring against him, calling them liars and hacks.
