Authorities in Tennessee have arrested a man who police say threatened to kill President Obama, 2012 Republican presidential nominee Mitt Romney, Rep. Paul Ryan and other officials.

Jimmie Randall Johnson Jr., 45, of Ardmore, Tenn., was arrested Saturday and faces a harassment charge. He is scheduled to appear in court Thursday, according to his case record.

According to a Davidson County affidavit, Johnson left three voice-mail messages at the main number for the Tennessee Department of Homeland Security this month with threats against Obama, Romney, Ryan ­(R-Wis.), state Homeland Security Adviser David W. Purkey and Tennessee Bureau of Investigations Special Agent Tommy Farmer.

Johnson threatened to “come with an AK” to kill the men, according to the affidavit. The next day, it said, he threatened to kill Romney and Ryan and “light Nashville up,” it said.
