The blog posts resurfaced during Mr. Hagedorn’s unsuccessful run for the House in 2014; he told The Star Tribune that they were old and had been satirical in nature. They surfaced again in 2018, when he won the seat chiefly by proclaiming his loyalty to Mr. Trump.

Complete information on his survivors was not available.

The final piece of legislation that Mr. Hagedorn introduced, on Feb. 9, was a resolution to place a national debt clock in the House chamber.

“The American people deserve full transparency about this nation’s fiscal affairs,” he said, “and this resolution will be a strong reminder to lawmakers as they vote on proposals that could put our country further in debt.”
