In 1978 Campbell founded the Community Law Center in Oakland, California, which she served for the next 18 years as its lead attorney. She practiced family law and worked on the needs of the working poor of her county in Probate Court. Between 1995 and 2000, Campbell was the General Director of her religious institute and oversaw its activities in the United States, Mexico, Taiwan, and the Philippines.
NETWORK
Campbell was first recruited to lead NETWORK in 2004 and continues to serve as its executive director. In March 2010, the United States Congress debated reforms to healthcare, known as the Patient Protection and Affordable Care Act. As a part of her work with NETWORK, Campbell wrote the "nuns' letter" supporting the reforms and asked leaders of women's religious orders to sign it. Sixty heads of religious orders and umbrella groups signed and the letter was sent to all members of Congress. The U.S. Conference of Catholic Bishops, the official voice of the Catholic Church in the United States, did not support the healthcare reforms. The letter contributed to the momentum in favor of the legislation. Campbell attended the signing ceremony for the law and received a hug of gratitude from President Obama. Campbell led the Nuns on the Bus project, in which she also participated. Campbell and a small group of religious sisters make tours on a dedicated bus to highlight social issues. In 2012, the first year of the project, the Nuns aimed to draw attention to nuns' work with the poor and to protest planned aid cuts. In honor of her advocacy work she was the 2014 recipient of the Pacem in Terris Peace and Freedom Award, which commemorates the 1963 encyclical of Saint John XXIII of the same name. Campbell addressed the Democratic National Convention held in September 2012.
Views
Campbell was targeted by then Pope Benedict XVI in his investigation of American nuns. Pope Francis, mindful of American Catholics' negative views on the criticism of their nuns, put an abrupt end to the Vatican investigation and welcomed their representatives to a conciliatory meeting. Unlike some members of the U.S. Conference of Bishops, Campbell supported the Affordable Care Act. both as a matter of social justice and as a better way to eliminate abortion rather than through criminalization. She said: "From my perspective, I don't think it's a good policy to outlaw abortion. I think, rather, let's focus on economic development for women and economic opportunity. That's what really makes the change." With regard to sexual abuse committed by clergy and covered up in the Catholic Church, Campbell noted in 2017 that she found it "outrageous" that the church was failing to sufficiently address sexual abuse and clerical accountability.
