Her religious congregation is the Sisters of Social Service (SSS). Their motherhouse is in Encino, CA and therefore is in the Archdiocese of Los Angeles. The Network hdq. is in Washington, DC, and is neither legally nor canonically "owned" by the SSS. So canonically, I don't even know who her bishop is.
It's mighty frustrating and perplexing for people who assume the Catholic Church is a monarchical, hierarchically-organized monolith, when actually it is quite crazy-quiltish in practice. Unless you're directly under the authority of a bishop (like a parish priest) it can be quite difficult to stop somebody by actually "firing" them. Who would do the firing?
