Clinton sent a blast email to supporters Monday afternoon asking people to sign up for her next venture, Onward Together.
"From the Women's March to airports across the country where communities are welcoming immigrants and refugees to town hall meetings in every community, Americans are speaking out like never before," Clinton emailed. "I believe more fiercely than ever that citizen engagement at every level is central to a strong and vibrant democracy."
