Rep. Jason Chaffetz (R., Utah) has released an office voicemail from March in which a man from Florida threatened to "hang [Chaffetz] from a lamppost."

"Hey Jason Chaffetz—I suggest you prepare for the battle, motherfucker, and the apocalypse," the caller yelled. "Because we are going to hunt your ass down, wrap a rope around your neck, and hang you from a lamppost!"

The man has since been arrested.

Chaffetz said that he wants police to do more to protect congressmen from potential violence. His statement came after the shooting of Rep. Steve Scalise (R., La.), who is recovering from a hip wound he suffered at the Republican congressional baseball practice in Alexandria, Va. last week.

Chaffetz appeared on Fox News on Thursday and discussed how this happens regularly to lawmakers without prosecution. He also described another time when someone threatened to slit his throat.

"There has got to be better ways to protect members of Congress," Chaffetz said.
