WASHINGTON (AP) The makings of a presidential ticket began in an unusual spot six months ago: a Minnesota abortion clinic.

At the time, it was a historic visit for Vice President Kamala Harris no president or vice president had ever made a public stop at one. But the visit laid the groundwork for Harris to connect with Minnesota Gov. Tim Walz and learn about his interest in reproductive health, an issue Harris has taken the lead on during her White House term.

At first glance, the 60-year-old governor might not seem the most likely of political surrogates to talk about abortion and pregnancy. But Harris found a partner who has a track record of increasing abortion access in his state and can speak comfortably about his own familys struggles with infertility.

Already, Walz has captivated crowds in Pennsylvania, Wisconsin and Michigan with the story of his daughters birth, made possible through in vitro fertilization treatments. The procedure involves retrieving a womans eggs and combining them in a lab dish with sperm to create a fertilized embryo that is transferred into the womans uterus in hopes of creating a pregnancy.

His wife, Gwen, went through seven years of fertility treatments before their daughter arrived. Phone calls in those years from Gwen often led to heartbreak, hes said, until one day when she called crying with the good news that she was pregnant.

Its not by chance that we named our daughter Hope, he told crowds in Philadelphia and again Wednesday in Eau Claire, Wisconsin.

The couple also has a son, Gus.
