Nuns on the Bus, organized by Sister Simone Campbell, are a group of sisters who have made it their life’s calling to battle poverty. Specifically, the nuns are protesting the Paul Ryan budget, saying it would:

Raise taxes on 18 million hardworking low-income families while cutting taxes for millionaires and big corporations.
Push the families of 2 million children into poverty.
Kick 8 million people off food stamps and 30 million off health care.
