Gallagher spent most of 2016 on the campaign trail, going to caucuses, primaries, debates and party conventions all across the United States.   
On July 3, 2019, Dianne posted a tweet about her miscarriage.
She wrote: "Last week, I had a miscarriage.
I didn't plan on publicly discussing the loss of our twins... but the silence & lack of "real" information surrounding losing a pregnancy made me feel isolated, exacerbating one of the most physically & emotionally excruciating times of my life."
She went on to say, "Physically, it’s a LONG process(not always over when it ends). Emotionally, my husband & I kinda feel like we’re in uncharted waters- which is weird b/c ~20% pregnancies end in miscarriage. I think I’d feel less alone if talking about something so "common" was, well, more common. I’m still experiencing the physical aftermath (yep. A week later, still bleeding. Had no idea how drawn out a miscarriage can be) but choosing to speak even a little, to be open about losing our twins feels like a good step for now." Gallagher ended with, "I don’t know what the next step is…that’s ok."
