Among all the Democratic speakers, Sister Simone Campbell, a leader of the "Nuns on the Bus," proved to be one of the harshest critics of Rep. Paul Ryan's budget.
Campbell and other Roman Catholic nuns traveled this past summer on a 2,700-mile trip through nine states to warn about the impact of the Ryan plan on the nation's less fortunate.
"Paul Ryan claims his budget reflects the principles of our shared Catholic faith," Campbell told the Democratic convention Wednesday night. "But the United States Conference of Catholic Bishops stated that the Ryan budget failed a basic moral test, because it would harm families living in poverty."
Campbell, who drew loud cheers, said the Catholic faith affirms "that we are all responsible for one another."
She spoke out for President Barack Obama's health care overhaul and urged delegates to join the Nuns on the Bus.
"I am my sister's keeper. I am my brother's keeper," she said.
