'My wife and I used I.V.F. to start a family.'

Democratic vice presidential pick Tim Walz is once again under metaphorical fire after his wife clarified that she never underwent IVF treatments to bear the couple's two children, as Walz has led people to believe.

In a statement to CNN published on Tuesday, Gwen Walz clarified that she and her husband used intrauterine insemination, not in vitro fertilization, to have children.

Gwen Walz characterized the IUI process as "incredibly personal and difficult" and as a "journey" of "desperation that can eat away at your soul."
