A Minnesota man who allegedly assassinated Democratic State Rep. Melissa Hortman and her husband is facing a slew of federal and state charges, including murder, after prosecutors revealed he may have been politically motivated and linked to anti-Trump protest movements.

Vance Boelter, 57, has been formally charged with six federal crimes, including murder, stalking, and attempted murder. Authorities say he shot and killed Hortman and her husband after visiting the homes of at least four public officials in a shocking rampage early Saturday morning.

Among the victims are State Sen. John Hoffman and his wife, who were shot but survived. Prosecutors say Boelter posed as a police officer, wearing a realistic silicone mask, and used a fake squad car to approach his targets. Two other officials escaped death only because they weren’t home.

“It is no exaggeration to say that his crimes are the stuff of nightmares,” said Acting U.S. Attorney Joseph Thompson at a Monday press briefing. “This was a political assassination.”

Before murdering the former House Speaker, Brooklyn Park police officers arrived at the Hortman residence, only to be met with gunfire. Boelter reportedly opened fire before storming the house and executing the couple.

Authorities say Boelter was armed to the teeth. Five firearms—including assault-style rifles—plus notebooks and “a significant amount” of ammunition were recovered from his abandoned black SUV, which bore a fake police license plate.

That wasn’t all.

According to the FBI affidavit, Boelter left behind a manifesto naming 70 political targets, including Minnesota Governor Tim Walz, Lt. Gov. Peggy Flanagan, and members of Congress. His vehicle was also filled with “No Kings” flyers, referencing slogans used at anti-Trump protests held across the nation that very day.

“When we did a search of the vehicle, we did find a manifesto that identified many lawmakers and other officials,” said Brooklyn Park Police Chief Mark Bruley. “We immediately made alerts to the state to provide security wherever necessary.”

The disturbing documents and flyers have sparked concern over the potential connection between Boelter’s political violence and far-left activism, particularly as demonstrations opposing President Donald Trump’s policies erupted across Minnesota over the weekend.

Boelter's family may have known something was coming. In chilling text messages cited by the FBI, Boelter’s wife reportedly warned relatives that “Dad went to war last night… I don’t wanna say more because I don’t wanna implicate anybody.” Boelter allegedly told her around the same time: “There’s gonna be some people coming to the house armed and trigger-happy and I don’t want you guys around.”

The FBI has not confirmed whether Boelter acted alone or with support from extremist groups, but the “No Kings” flyers and anti-Trump slogans discovered in his SUV have drawn serious scrutiny.

Authorities are urging caution at future protests, especially those targeting the Trump administration’s policies, as federal agents now investigate whether these demonstrations may have radicalized the alleged killer.

Boelter was captured Sunday after a two-day manhunt and appeared in federal court Monday afternoon in St. Paul. The DOJ has not yet announced whether it will pursue the death penalty, though Thompson said it's “too early to tell.”

As for the political climate, leaders on both sides condemned the attack, though many conservatives have pointed to the deafening silence from far-left organizations that routinely claim the moral high ground on political violence.
