Both Harris and Trump talk about the cost of insulin, but advocates say a law Walz signed does more

In June 2019, Lija Greenseid handed Minnesota Gov. Tim Walz an empty vial of insulin that her 13-year-old daughter had painted gold.

Greenseid's daughter has Type 1 diabetes, which means she requires daily injections of manufactured insulin to stay alive. The price of a single vial of insulin rose by about 1,200% between 1996 and 2018, and the gold vial was a reminder, Greenseid said, that this lifesaving pharmaceutical shouldn't be as expensive as precious metal.

"What I heard is that that gold vial remained on his desk at the governor's office, and he brought it up throughout that summer and fall when he was trying to talk to legislators to get them moving," Greenseid said.
