MINNEAPOLIS (AP) — The man charged with killing one Minnesota lawmaker and wounding another in what prosecutors have described as a meticulously planned attack, had dozens of apparent targets, including officials in at least three other states.

Minnesota Rep. Melissa Hortman and her husband were shot and killed at their home early Saturday morning by a man disguised as police, officials said.

Boelter allegedly had firearms and a list of 45 elected officials in notebooks in his car, law enforcement said.

Gilbert, the golden retriever trained by murdered Minnesota lawmaker Melissa Hortman, had to be put down after the shooting that killed her and husband Mark at their home.

Officers found notebooks referencing at least 45 state and federal elected officials in the car of suspected Minnesota shooter Vance Boelter, according to Joseph Thompson, the acting U.S. attorney for the District of Minnesota.

Members of Congress will attend emergency briefings this week after the killing of a Minnesota state lawmaker brought renewed fears — and stoked existing partisan tensions — over the security of federal lawmakers when in Washington and at home.

Plus, Republicans in the Senate Finance Committee proposed changes to Medicaid and a lower SALT cap in their proposed revisions to the bill for Donald Trump's agenda.

Vance Boelter was charged in the shooting of two Minnesota lawmakers. Iowans were on lists found in his notebook, police said.

State lawmakers’ addresses have already been removed from the Minnesota Legislature’s website, and the Capitol saw a larger security presence than usual on Monday.
