Minnesota State Representative Melissa Hortman and her husband, Mark, were remembered at their funeral on Saturday as “extraordinary public servants” who were killed in an inexplicable act of political violence.

Their wooden caskets rested side by side inside the Basilica of St. Mary in Minneapolis as hundreds of political colleagues, friends and relatives sat shoulder to shoulder in the pews to say goodbye to the couple, who were assassinated at their suburban Minneapolis home earlier in June.

Former President Joe Biden and former Vice President Kamala Harris joined the mourners for the somber Catholic funeral Mass, though neither spoke during the service.

Gov. Tim Walz of Minnesota, his eyes red from crying, delivered the eulogy. He praised Ms. Hortman as a consequential and compassionate political leader and Mr. Hortman as her proudest supporter. He said their shared legacy included improving roads and bridges, and free school lunches and expanded preschool for children.

“Millions of Minnesotans will get to live their lives better because she and Mark chose public service,” Mr. Walz said.
