A North Dakota resident is facing charges for allegedly threatening the life of former President Donald Trump, with online posts including ominous messages like “can you feel my footsteps coming?”

Andrew Walter Sandvik is charged with attempting to influence a federal official through threats, as detailed in a criminal affidavit accessed by Law&Crime. His exact age has not been disclosed.

According to an FBI agent’s affidavit, a detective from Fargo alerted authorities on September 4 about Sandvik’s “alarming online posts” that were aimed at Trump and law enforcement. These posts featured a profile image of an individual closely resembling Sandvik, who was wearing a beanie.

The affidavit reveals that one of the posts appeared to threaten local police, while another insinuated the construction of a bomb. Investigators were tipped off by a witness familiar with Sandvik, who also identified his residence.

On September 17, law enforcement officials interviewed Sandvik, focusing on suspicious items such as cinder blocks and bottles filled with liquid found at his camper on his mother’s property. Although no wires were observed emanating from the bottles, authorities discovered Sandvik had made additional “more troubling” posts targeting Trump and FBI Director Kash Patel.

“Secret Service it is no secret I am your biggest threat you better get here fast,” read one post in all caps, with another calling for the FBI, CIA, and foreign intelligence services to “come get me!”

“Trump, Can You Feel My Footsteps Coming?” reads another, followed by the words, “Death is now marching towards the failed and weak Donald Trump!” Sandvik also allegedly posted, “Patel IM WAITING FOR YOU.”

A website was referenced in at least one of the posts, with its URL containing the suspect’s last name, according to investigators. The site, which was later financially tied to Sandvik, contained more “concerning posts of violence,” authorities said.

“Law enforcement, U.S. Military and National Guard STAY HOME!” read one followed by the words, “You will die an angel’s death if you attempt to protect Donald Trump.” Another mocked the death of the late activist Charlie Kirk.

More posts were investigated. One read, “Trump is weak and will be destroyed soon,” while another stated, “Trump’s Blood Judgement Is Here! … You will soon find yourself without insides as they will be pulled from your body while your limbs are ripped out of their sockets.”

After speaking with witnesses, authorities determined the posts were made by Sandvik and that he had also painted Airsoft guns black to “appear as realistic as possible.”

Sandvik was arrested, and he was scheduled to make an initial appearance in federal court on Friday.
