FBI agents have arrested two people in Michigan for making election-related threats, Paralel.Az reports citing The Detroit News.

The Michigan-based outlet says one suspect was linked to an assassination plot targeting Donald Trump.

The man, Isaac Sissel, allegedly posted on Reddit under the username "ShootUpTrumpRally" and has since told investigators he believes "everything would be better if Trump was dead".

In the second criminal case unsealed on Tuesday, Christopher Clay Pierce, 46, of Jackson is accused of making threats against an unidentified political action committee (PAC) affiliated with the Democrats over the past two years.

Pierce had reportedly previously been warned by the FBI that he could be charged with a crime if he continued posting threats online, but continued to harass the Democratic-aligned group.
