Accused political assassin Vance Boelter allegedly sent a deranged confession to FBI Director Kash Patel claiming that Minnesota Gov. Tim Walz had urged him to kill Democratic lawmakers as part of a twisted plot.

The wild, handwritten ramblings were released Tuesday as Boelter was indicted for allegedly gunning down ex-House Speaker Melissa Hortman and her husband, Mark, in their Minneapolis home on June 14.

“Dear Kash Patel. My name is Dr. Vance Luther, Boelter E.d.D. I am the shooter at large in Minnesota,” Boelter allegedly wrote.

He went on to claim he’d been “hired by US military people off the books” since his college days — and had gone to work on “line of duty” missions across the world.

“Recently, I was approached about a project that Tim Walz wanted done … Tim wanted me to kill Amy Klobuchar and Tina Smith. Tim wants to be a senator,” he claimed, referring to Minnesota’s US senators.

Elsewhere in the ramblings, he alleged: “I told Tim I want nothing to do with it and if he didn’t call off that plan I would go public.”

The note, which was first reported on last month in the wake of his arrest, was found in his abandoned SUV at the crime scene after he allegedly gunned down Hortman and her husband.

Boelter allegedly shot state Sen. John Hoffman and his wife, Yvette, earlier that night but they miraculously survived.

The letter didn’t disclose why Boelter allegedly targeted the two couples.

He insisted to The Post last week that the murders had nothing to do with President Trump or abortion — but stopped short of saying what allegedly drove him to kill.

“There is little evidence showing why he turned to political violence and extremism,” acting US Attorney Joseph Thompson said following his indictment.

“What he left were lists: politicians in Minnesota, lists of politicians in other states, lists of names of attorneys at national law firms.”

Asked for comment on the letter, a spokesman for Walz told the Washington Post, “The tragedy continues to be deeply disturbing for all Minnesotans.”
